The machine won’t start what to do


Agree, it is not especially pleasant and comfortable if you failed to start your car in the morning. Why the machine won’t start? What to do in this case? Do not despair, not all causes require a call to the service center to the specialists. You can identify the problem and eliminate it yourself.

If you are certainly confident in your abilities, the main thing in this case is to do no harm. If the car does not start in the winter, you should call the service heater cars and specialists will find out the reason for the lack of starting.

Several basic parameters are essential for a successful engine start: a normal supply of oxygen (for combustion), a good spark (for ignition) and fuel (to run the engine).

If the car does not start, inspect the air filter. After all, for a positive start of the engine it is necessary to have a sufficient amount of oxygen. If the air filter is worn or clogged with dust and dirt, the engine can not fully “breathe”, it entails the absence of starting the engine. It makes sense to check the air intakes and air ducts, and they can be clogged with dust.

If it’s not the filter, air intakes or ducts, you should inspect the vacuum lines of the engine intake system for leaks. Because of their deformation, the excess oxygen will get into the intake system, and therefore the car will not start.

To do this, unscrew the spark plug from the engine and connect to the high-voltage wire. Then you need to put the spark plug on a metal surface of the engine and turn on the ignition, if everything is ok you will see a spark between the spark plug and the surface. Be careful not to get any flammable liquids on the surface or the candle. Do not touch the wires and plugs when turning on the ignition.

If the plugs are serviceable and the air flow is sufficient, the car still does not start, the likely cause of the lack of engine starting may be a failure in the fuel system. You can check the correct operation of the fuel system and an ordinary medical syringe filled with fuel. Then you need to inject gasoline into the throttle, turn the ignition key, start the starter. You should not use this method if you do not have the appropriate experience.

And accordingly, in case of significant deviations from the norm the fuel pump is out of order, contact the specialists.


There are very few reasons for this, you can say one. a faulty or dead battery. Measure the voltage, check the high-voltage wires and terminals for contamination.

Given the speed of modern life and the need for mobility in movement, do not waste time, call the experts and go about your business. After all, everyone’s got to do their own thing.

Have a good start and safety on the roads.

All winding machines are similar to each other, each car not starting glitch in its own way.

machine, start

Always Volga in.40 started, spark plugs have never failed, but you can have a spare set (240r.), Battery Charger (1500r.), if you’re not sure, take it into the heat (or if not at home), and a bottle of warm water on the manifold if it’s really hard to start (free).

They will tell you that your crankshaft is frozen to the crystal lattice of metal and that only disassembly and assembly of the engine with infrared heating will help. That’ll be 25,000.

The car does not start. Starter or battery? What to do if the car won’t start?! Or about saving laziness. How to Check the Battery and Related Items? How to service a serviceable battery.

Tips on the drive, as always amaze me. People are ready to recommend anything, not even trying to go into the problem. Yes, and, actually, it is not surprising, so at us and in HUNDREDs the cars are repaired. Getting into the deep end right away instead of digging in and figuring it out.

So this time the man had a diesel Audi A4 quattro that wouldn’t start. He tried to start with a cigarette lighter, it did not work, and that was enough for the man to conclude that it was necessary to remove the starter from the car for repair. And the only thing that has forced to write on a drive it is complexity of this procedure on his car. For more details, see here.

What to do if the car will not start? Where to start?

First, it is necessary to understand if the starter motor starts or not. If when you turn the ignition key nothing happens, the dashboard goes out or you hear a rattle, it could indicate: a completely drained battery; a fault in the wiring; a faulty starter; other possible causes.

Today we’re going to talk about a case where the starter doesn’t crank.

It is necessary to service the battery to have long life and not to bring surprises with cold weather, especially if your car is operated mostly in the urban cycle (50/50) and you do not use the car much. For example, if the out-of-town trip is less than 14 kilometers per shoulder.

We’ll talk more about how to service the battery and how to start the car in cold weather next time. Now let’s talk about what to look at first before you go any deeper.

BATTERY. You need to make sure that it works. Check voltage on battery terminals. working battery must be at least 12,6V.

Checking the voltage on the battery terminals. On the working battery must be at least 12,6V. Be aware that there may be an error in the gauge.

But that’s not enough, you need to check the battery with a load fork. It tells us if the battery has enough power to start the engine. It simulates the load on the battery when you start the car, within 5 seconds the voltage on the load fork must not drop below 9.6V (75% of charge) fully charged battery. 10.2V or higher. Do not hold the plug longer than 5 seconds.

Important. Check not a fully charged battery Check the battery and if it is cold, remove the fuses positive temperature. Do not check a cold battery. Risk of battery explosion.

The first two items can tell you that there is a problem with the battery and it needs either a deep recharge or replacement. In some cases when the battery is serviced it is necessary to add distilled water to the battery cells.

A serviced battery must be recharged by removing the battery plugs. Be careful not to get burnt by the electrolyte. Before charging, check the electrolyte level, add distilled water if necessary.

How to Check a Battery and Related Items? A special tool to unscrew the plug of the battery to be serviced.

In this case, each of the 6 battery cells has its own level. It is not enough to check and add distilled water in one cell only.

How to Check the Battery and Related Items? Checking the electrolyte level in the battery. Where is the level at which you need to add distilled water.

In this photo you can see the level at which you need to pour distilled water into the battery if necessary.

The interesting fact that shows up on my own experience, the original batteries live much longer than the non-original. The same VARTA or Bosch in the original serve from 8 to 10 years, the batteries are not original under the same brands rarely serve more than 5 years (the experience of WAG, Volvo and FORD).

Inspecting the battery terminals. They should be free of oxide. They must also be screwed in well. They should not rotate, let alone be removed by hand. In the summertime this contact might be enough, but in the wintertime it might be a surprise. Although in summer it is not desirable, since the excessive resistance creates unnecessary load on the starter, which can lead to failure of its or other components.

If you don’t service the car yourself, be sure to ask for the terminals to be checked and serviced at the service.

On the left side of the picture we see the battery terminal treated with a protective compound. On the right-hand side, the battery terminal is quite run down (though less oxidation can cause problems if the temperature drops)

Battery grounding point. Inspect where the negative battery cable connects to the body. There should be no traces of oxide on the place of connection. It should be firmly bolted to the body. Otherwise it can be the source of many car problems, such as bad battery charging and others. It is also better to protect it with a protective composition.

Check underhood fuses for continuity.

Inspect the wires running from the plus terminal to the starter, make sure there is no damage. At the connection to the starter must not be oxide.

Caution! If you unscrew the wire, be sure to remove the minus terminal from the battery. Risk of locking and vehicle fire.

Another reason for not starting may be a false alarm or a tag. Make sure the vehicle is disarmed. The problem could be a regular battery in the remote control or a tag. Just because you have a light on the remote control when you press it, it does not mean that the battery charge is sufficient. The battery costs a penny and it is better to replace it than to go deep into the car.

Another problem with not starting the battery may be a dead battery in the remote control or a tag.

Not starting the car automatic what to do

In winter many Russian motorists face a situation when the car won’t start. Possible causes of malfunction, what to do if the battery is dead. RIA Novosti, 16.12.2021

MOSCOW, Dec. 10. RIA Novosti. In winter many Russian motorists are faced with a situation when the car won’t start. Possible causes of malfunction, what to do if the battery is low, why the car can not start after a short stop, as well as expert advice. in the RIA Novosti story.Why the car does not startAll malfunctions that prevent the engine from starting can be divided into two large groups: the starter does not crank, but the engine does not start, and the engine does not start because the starter does not crank.In the first case, problems may arise for the following reasons:In the second case:Generator or batteryGenerator. is a device that converts some of the energy produced by the engine into a charge for the battery. If the alternator is faulty, it cannot charge a dead or partially discharged battery. As a result, the starter does not have enough energy to start. In this situation a dead battery will not start the starter and the dashboard will not illuminate.If there is still power, the instrument panel will alert the driver to the lack of charge with a blinking icon. The vehicle can be started with a “cigarette lighter” from another battery, but the driver will immediately realize that the charge is half-powered and there will be no “current” again after parking. If the alternator is out of order, it must be replaced. Before you decide to drive on your own, it is important to check the alternator belt, if it is damaged. call a tow truck, because the belt affects the engine cooling system, the engine can overheat.Old batteries discharge faster in the cold. After three to five years of service, any batteries are at risk. Therefore, the car after a frosty night may not start, especially if there are constant sources of consumption in the onboard network (e.g., a working recorder or alarm system).”It is sometimes possible to prevent a battery breakdown by indirect signs:Konstantin Epaneshnikov, Service and Spare Parts Director at Avilon Volkswagen, warns: “Frequent and short trips lead to a low battery. So the battery is discharged and has no time to recover. In winter it is especially important, as the car is often driven with a heater, which severely loads the battery.”.StarterSmall electric motor that transmits torque to the crankshaft to ignite the fuel is called a starter. If the driver, turning the key in the ignition, hears an unusual click or silence, then the breakdown should be sought in the starter. Sometimes it starts working only after a few turns of the key or very reluctantly starts the engine, although the battery is charged.In this case, the causes can be many: from oxidation of contacts and short circuit wiring to crumbling bearings and brushes.The ignition switchThe first signs of failure of the contact group of the ignition switch. failure of the whole chain of several electric devices, since each contact of the chain is energized by several electric consumers. For example, turn signals, reversing lights, dipped beam and high beam stop working, it means that the contact to which they are bound, burned out or oxidized.if after turning the key the engine does not start, it is necessary to have a look at the contact group of the lock. Most often its contacts are damaged during engine start-up due to increased overheating, voltage spikes, sparking after washing the car. In some cases, it is enough to sand down the contacts, if the lock is old, it is better to change the group completely.Gasoline and dieselDiesel engine differs from the gasoline engine by the lack of spark plugs and the principle of ignition of fuel (from compression). The main reasons why the diesel car does not start. fuel freezing and low compression.It is necessary to use winter fuel at minus temperatures, as summer fuel gets thick on frost and paraffins, which are in its composition, precipitate and clog fuel hoses and the filter. To cope with the problem, you need to warm the car in the garage and pour a special additive into the tank, preventing thickening. After that it is better to drain and exhaust the rest of the diesel and refuel with a special winter fuel.Spark plugsEach automobile manufacturer specifies the interval for checking and replacing the spark plugs, which should be adhered to. The vehicle may fail to start due to fouling of the spark plugs (poor-quality fuel was used), flooding with gasoline (when trying to start the vehicle for a long time without success), as well as worn electrodes or spark plug connectors.The same situation is also relevant for vehicles with electronic injection, when the driver repeatedly presses the gas pedal, flooding the spark plugs with fuel.Valve timingIf the starter cranks well but the engine won’t start, the timing may be off. This is due to improper adjustment or damage to the timing belt or chain. If these parts are stretched or torn, the valves do not close in time, the compression and combustion of the mixture does not occur, the car will not start. The pistons can reach the valves and bend them, resulting in costly engine repairs.It is important to adjust the belt or chain correctly according to the marks and replace them in time.Engine compressionLow compression occurs due to wear of the cylinder piston group or corked rings. In the first case, only an engine overhaul helps, but the car can be protected from the second with the correct preventive maintenance. There are special liquids that flush the oil system and remove carbon deposits.Alarm systemAn alarm system performs two important functions: it protects the vehicle from theft and blocks the engine start in the event of critical malfunctions.Since it is a complex electronic system with its own “brains” and many levels of tamper protection, it can malfunction and block the engine. A few reasons why this may happen: In some cases, simply replace the battery in the key fob, in a more complicated situation may require computer diagnostics “alarm”.ImmobilizerStarter firmly cranks, but the engine does not start. This can happen because of the immobilizer, which is controlled by the alarm keyfob. Often equipment malfunctions or accidental presses on the key fob activate the anti-theft protection and the immobilizer blocks the starter, ignition system, injectors or fuel pump. You can remove the protection by finding out the correct combination of buttons or by contacting a competent electrician.ElectricsThe clamps and terminals in the electrical system are susceptible to oxidation or loosening due to constant microvibration. Problems can be corrected by cleaning the terminals with a brush or sandpaper and using special lubricants. If the clamp is clean it is necessary to move it and press to restore contact. If there is a greenish or white film on the battery at the connection point of the wire, it is necessary to tighten the clip.Crankshaft SensorThe Check Engine light on the dashboard is on, the starter fires, but the engine will not start. Crankshaft, camshaft, idle speed, coolant temperature sensors are defective. Change the unit to correct the problem.Flywheel crownCheck Engine does not start if the starter is working, because of the wear of teeth of the flywheel crown and bendix. You can detect a malfunction by ear: a “click” is heard when turning the key in the ignition to the extreme position. The intake relay is operating and the bendix is moving toward the flywheel. The starter does not rotate, the engine does not start and a characteristic rattle can be heard. If the wear on the teeth is not too severe, you can still try to start the car by cranking the starter a few times, but do not forget that there is a danger of discharging the battery.Gasoline pumpDmitry Matveev explains the possible problems with the gasoline pump: “The pump malfunction can be gradual or instantaneous. Instantaneous threatens fans of driving on a light bulb (keep a minimum reserve amount of fuel in the tank). If you drive constantly from refueling station to refueling station, the pump overheats because the minimum amount of fuel does not wash and cool it, which leads to jamming of the device.Gradual malfunction is manifested by pressure drop, when the pump is not pumping the pressure declared by the manufacturer. It happens because of untimely filter element replacement and low-quality fuel, which is enriched with additives that destroy the bearings”.Exhaust pipeCondensate forms in the muffler because of temperature difference. In warm weather it can lead to corrosion, in winter the car may not start because the fluid is frozen. Ice formed in the exhaust pipe, blocks the exit of gases and the engine does not start.If the ice is in the end of the pipe, you can punch it with a screwdriver and start the engine, the remaining ice particles will melt. If it is iced deep inside, only a warm garage will help.To start the engine, several conditions must be met in order for the engine to start:In frostFreezing temperatures all fluids thicken, and some freeze. This also applies to engine oil.In order to start the car in freezing temperatures, you need to perform a few simple actions:If possible, at serious sub-zero temperatures, it is best to keep the battery warm by removing it from the car. In addition, many motorists use special additives that are poured into the fuel system or carburetor, which facilitate starting the engine in winter.”To ensure that the engine is started without problems, you must:” On a hot “The main reasons why the vehicle does not want to start after a short parking lot:After repairAfter the overhaul of the engine before its first start you need to make sure that the battery is fully charged, since the resistance of new parts is high enough, then pour the tosol and oil, checking the oil level in 10 minutes. The oil pressure indicator must light up and go out after a maximum of four seconds. After that you can start the engine.The engine must warm up to operating temperature at idle speed. After warming up it is important to check the oil and coolant level, check the tightness of connections.What to do if the engine stalls at onceThe main reasons for such engine behavior include:In the first case, you need:In the second:

The car starts, but immediately shuts down. causes and remedies

This is another problem, which car owners occasionally face. Some causes are similar to when the car simply does not start. for example, a fuel pump failure, air lock in the fuel supply system, clogging of the fuel filter. But there are other reasons why a car starts, but immediately stops. Consider the most common ones.

Faulty immobilizer. Glitches with the immobilizer can occur for two reasons: the ignition key, which has an integrated chip with an electronic code, battery died and the immobilizer does not allow the unknown key to start the engine, or the elements of the immobilizer are out of order. In the first case it is enough to replace the dead battery, but in the second case you should call in service stations, make immobilizer diagnostics and re-flash the device.

Failure of idling valve. If the parts of the valve are clogged with combustion products, the engine electronic control unit (ECU) receives erroneous readings. Electronic brains of the engine perceive it as a malfunction and disconnect the power unit. In this case it is necessary to clean the valve after which it is important to adjust it correctly. If cleaning does not help and the valve is defective, it should be replaced with a new one.

The valve of exhaust gas recirculation system is clogged. The elements of this valve (pipe, plate, seat) are periodically clogged with carbon deposits, which occurs due to using low quality fuel. As a result, the valve gets jammed, which prevents the EGR system from working efficiently and the engine crashes right after the ignition is turned on. Valve cleaning is recommended (regular cleaning interval is every 100 kms). Change the valve for a new one or replace it with a new one.

The valve in the exhaust gas recirculation system is clogged

Lambda probe failure. The oxygen sensor, aka the lambda probe, can be damaged if you periodically refuel your vehicle with low-quality fuel with high lead content. As soon as this sensor fails, the engine ECU receives incorrect information about the quality of fuel-air mixture, and shuts down the engine. There’s only one recipe: replace the broken lambda probe.

Crankshaft position sensor failure. If this sensor is broken, which sends information to the ECU about the position of the pistons in the engine cylinders, then the electronic “brains” of the engine disconnect it at idle speed. The reason of sensor breakage is its wiring failure under the influence of reagents or burnout due to a short circuit in the car’s onboard network. The Wood-Polymer CompositeB can not be repaired, it has to be replaced.

Problems in the fuel system

A common cause of engine starting problems is no fuel in the engine cylinders. The engine is revving but will not start.

Determine if there is a problem with the fuel system by looking at the exhaust pipe while trying to start the engine. If there is any color smoke coming out of the exhaust pipe when the engine starts, it means there is fuel in the engine cylinders. If there is no smoke, there is no fuel in the engine and you need to look for the cause.

Check first of all if there is gasoline or diesel fuel in the tank, it is possible that the fuel level in the tank is at zero, and you just did not notice it. If you have run out of fuel, call a cab and go to the nearest gas station with a fuel can. It used to be that many drivers who were left without gasoline would ask passing drivers to share their gasoline. Nowadays most modern cars have such a device of gas tank, which does not allow you to stick a hose through the neck, so this method of solving the problem with an empty tank is almost a thing of the past.

Cars with diesel engines have inappropriate or low-quality fuel that can dramatically harden in cold weather, and paraffins in it precipitate, clogging the fine filter and fuel lines. To solve this problem, you can try to warm fine fuel filter with a hair dryer, if it does not help. You’ll have to warm the car up in a warm garage. After that, drain the rest of the summer fuel and fill up with winter fuel. You can also fill a special anti-oil additive into the tank.

The cause of the car not starting may be a failed fuel pump or its relay. The fuel pump can fail if the car’s driver is in the habit of driving with minimal fuel in the tank. The fuel pump is cooled by being submerged in fuel, if there is not enough fuel in the tank the pump overheats and can fail over time. Impurities in low-quality fuel or frozen water can clog the fuel pump filter screen, resulting in engine start-up problems.

To check the operation of the fuel pump, listen for a buzzing sound coming from the rear seat for a few seconds after the ignition is turned on. To repair the fuel pump or replace its filter, you must remove the rear seat cushion, open a hatch in the floor, and then remove the pump. You may need to call a service center for this job.

The cause of problems with starting the engine may be a damaged fuel hose. You can tell if the fuel hose is damaged by fuel leaks and smells.

The main reasons of refusal to start the car

Most dangerous is such a car breakdown in winter, although the car often does not start in the summer for the same reasons. Let’s start with the simplest situations:

  • Running out of fuel. A mistake made by many young motorists. Just turn on the ignition and check the fuel gauge.
  • Poor fuel quality. Happens more often in the winter if there’s a lot of water in the gasoline. If so, the engine will sneeze and smoke black, and the fuel system may freeze. Can be corrected by flushing the system and filling with quality fuel.
  • Poor quality / low level of technical oil or poor oil supply. Oil changes its consistency in cold weather and thickens, making it hard to start the engine. If it is dirty or has not been changed for a long time, there will also be problems. The oil must be changed to an all-season quality oil.
  • the alternator belt is worn or loose. The belt does not transmit torque to the shaft, and the car does not start. If you don’t want to “lose” the cylinder block, change the belt in time.

If the listed symptoms are eliminated, but the car engine does not start, it is necessary to move on to more complex causes of failure.


Problems with the starter can lead to unpleasant situations on the roads, and to solve them you need to use two methods.Take the car to an automobile repair shop for diagnostics by specialists.Even if the car still does not start at first attempt, we recommend that you correct the problem as quickly as possible, by following the sequence below. It is also possible that the malfunction is due to a clogged fuel filter that also needs to be serviced.Weak battery also causes this problem, so it must be corrected. You should also make an inspection of the throttle valve on the car.As statistics show, this problem often occurs at negative ambient temperatures. But even in spite of external conditions, it is necessary to act exactly the same. Many drivers rely on fixing the problem themselves, which is considered a gross mistake. Brand of the car does not affect this malfunction, but sometimes it occurs because of the design features of the vehicle. You can turn to the Internet and there to find out a lot of useful information, but if there are doubts, it is better to use the help of an auto mechanic. Drivers often refer to this problem as “the starter is malfunctioning and the car won’t start” and “the car doesn’t start right away”.By and large. it is the same malfunction, which says that the car is not able to start. Reasons for failure may be the following: malfunction of fuses, there is rust on the battery, discharged battery, ignition coil does not give out the spark, on the inner surface of the hood there is condensation, fuel system malfunction vehicle. Breakdown of the starter is the most common cause of malfunction in the ignition system of the vehicle. You need to know how to check this part for serviceability.In new foreign-made cars the starter most often breaks down because of low lubrication or dirt. For such cases, it is recommended to remove it, disassemble it and clean it from foreign debris. The amount of lubricants must be supplemented. Do not forget that it is better to remove the starter from the car before the work.


If there is no possibility to make a repair in a car repair shop, you will have to fix it yourself. This does not require any special skills. First of all it is necessary to clean contacts of the battery. The car’s spark plugs should also be checked and cleaned of dirt. Bad and dirty starter pins can also be the cause of engine failure. The best way to find the fault is by elimination method. The fuel system also plays an essential role in the operation of the car. If the starter works well, at the moment of engine failure, check it.It is a carburetor, a special pump and an injector. The best place to start is with the pump. On some cars, it may be electric. When turning on the ignition, you should hear the sound of the motor running, if it is not heard, then it may have burned out. Also the lack of voltage can stop its operation. In this case, you need to check the fuses. On carbureted cars, on the contrary, it is necessary to check the mechanical pump. To find out about its working condition, you can use the hose of the pump or carburetor exhaust connection. Using a special crank, watch the condition.If the gasoline starts splashing out of the pump, then the whole system is working properly. Injector vehicles, carry out a similar procedure. The only difference is the location of the nozzle. As soon as the valve is pressed, gasoline spurts out of the hose. The fuel must be under high pressure in the gasoline pump.In this case it is possible to judge about the serviceable technical condition. If after these procedures the engine also does not start, it is better to go to a specialist. The vehicle’s carburetor needs to be fully diagnosed in a car repair shop.It is practically impossible to do such a procedure by yourself. It is carried out with the help of special equipment. Replacement and diagnosis is quite an expensive process, so it is necessary to choose a good repair shop. Many experts point out that in order to eliminate such defects it is necessary to regularly perform an initial technical inspection of the car.

The starter often fails in cars of any manufacture. It does not have enough force to rotate and thus to drive the engine. To solve this problem, you need to know all the vulnerable places of this part of the machine. The driver is required to check the operation. The starter on foreign cars is more finicky than on domestic cars.For troubleshooting, it is recommended to remove it from the car and perform a complete cleaning of the housing and mounting elements. The old grease must be carefully removed from the part. It is easy enough to do, but you should not abuse it. You can check the starter for the noise level. If you hear a click when you try to ignite, and it does not spin, then the cause is in the relay. So here you will only have to replace or repair it. But you should remember that the relay is repairable if it is disassembled into its component parts.

Diagnosis and repair of the auto start system

Diagnose failures of auto-start system consistently. this will quickly identify and eliminate the cause of failure on the basis of the results.

Checking the battery

Weak car battery disrupts trouble-free operation of auto-start. That’s why it is better to start checking with the battery. It is necessary to examine battery, terminals and connections, check electrolyte level inside, check charge level with multimeter (should be not less than 13.5 В). If the case is damaged, replacement of the battery is necessary, contacts are cleaned up, electrolyte may be refilled to the level, connections are secured. In case of weak charge it is necessary to recharge the battery correctly.

Check the working condition of the remote communicator

You need to conduct visual inspection of the device, check the condition of the buttons and contacts, check the charge level of the battery. In case of minor defects the unit is disassembled, dried and cleaned, worn and damaged components are replaced and re-soldered.

Installing the bypass

In the processor module of the immobilizer bypass (in the module of the flat antenna) you must install and fix a spare key, then, the unit is closed with a cover and installed behind the central console of the instrument panel (by the car stereo or ashtray). Then connect the block with the contact “” (red contact) to the power and ignition switch (12 V), and the contact “-” (blue contact) to the remote start system output. The grey contact is connected to an external antenna adapter or standard RFID adapter.

Washing machine won’t start

Check the temperature sensor

The sensor is installed on a pipe sleeve cooling system or in the cabin of the car, and its connection (cable, plug) should always be checked if the engine starts with a charm, but does not start when you set the temperature start mode. You should also check the electrical connections and clean any oxidized contacts.

If the vehicle starts and immediately shuts down

If the car starts and stops after a few seconds, the causes, regardless of the time of year, may be:

  • False alarm (security system)
  • Clogged idle valve, air or fuel filter
  • poor quality or contaminated fuel
  • airlock in the fuel line
  • fuel pump malfunction
  • malfunction of various sensors. oxygen, EGR, crankshaft position

The list of causes can be more. Therefore, if independent attempts to determine the cause of the problem and its solution were unsuccessful, it is worth turning to experts.
