Car Suddenly Stalls Will Start Again but Dies

What could be more irritating than a auto that starts for a couple of seconds so shuts off completely, and this happens every time y'all try?

Not a lot of things if you ask me! You should know that it is a quite mutual problem, so you lot are definitely non solitary, and there are some piece of cake fixes to this.

In this article, we volition go through the ten most common reasons why your car starts then dies immediately. So allow'southward brainstorm with a quick look at the almost mutual reasons why this problem would occur.

The about mutual reason a car starts and so dies immediately is a lack of fuel injected into the engine. It can also be a faulty immobilizer not recognizing the car key. The lack of fuel event is most often caused by a clogged fuel filter or a bad fuel pump.

All the same, these are just some of the most common causes and there are really many more. Here is a more than detailed list of the most common reasons why your motorcar starts and then dies:

ten Causes of Motorcar Starts Then Stops Immediately

i. Lack of Fuel

The most common reason why your car starts so dies is because of a lack of fuel in the engine. This does oft happen considering at that place is a pocket-size amount of fuel in the fuel rail, which helps the engine start, but there is no fuel pressure to keep the engine alive.

Lack of fuel is pretty easy to locate, though. Either yous can connect a fuel pressure level gauge on the fuel rail or lose a bolt there carefully when yous creepo the engine to meet if you have any fuel pressure. Be careful, so you do non gear up anything on fire, though.

If you realize your car has depression fuel pressure, yous tin check out our other article about Low Fuel pressure.

2. Anti-Theft Warning System

The second virtually common affair is any problem with the immobilizer or anti-theft alarm arrangement. When the anti-theft system is activated, the car will non send any ability to the fuel pump, which builds fuel force per unit area in the fuel rail. This will cause the car to outset for some seconds, as we talked nearly before.

If the anti-theft alert organization is from the mill, you should have a central symbol on your dashboard that should turn off a couple of seconds later on turning the ignition. If it is not – try to lock and unlock your motorcar and try again. If information technology'due south still lightened up, there might be a problem with your auto key.

If you lot accept an aftermarket anti-theft alarm, there might actually be a problem with the alarm itself or a bad remote.

3. Dirty Fuel Filter

If the motorcar stops later on turning on the ignition, the problem could lack fuel, as nosotros talked almost before. A fuel filter is a widespread affair that causes low fuel force per unit area.

The fuel filter is a filter that you should replace after a schedule, which depends on your car model. If you haven't replaced it for a long fourth dimension, it might actually be clogged.

Fuel filters are often quite easy to replace and not very plush. If you take low fuel pressure, information technology can be worth trying to replace it.

4. Bad Idle Control Valve

The idle control valve'southward role is to keep the idle steady of your car. Newer cars control the idle with the throttle body, only if you accept an older car with a steel wire to the throttle body – you accept an idle control valve.

Often this idle control valve can get dirt, and this will crusade the idle not to work properly. You tin can try to make clean this valve to see if it gets better. Otherwise, you have to replace information technology or repair the wirings to it.

5. Vacuum Leak

The throttle body or idle control valve controls the idle by regulating the amount of air entering the intake manifold. If y'all accept a major vacuum leak, this can actually cause the car'southward air-fuel mixture to become as well lean and dies later on a couple of seconds every fourth dimension you try to first your machine.

Vacuum leaks are often quite piece of cake to locate, either using an EVAP smoke car or just listening for the leak, as it volition often cause a high pitching sound.

six. Faulty Spark Plugs

The combustion engine works by igniting an air-fuel mixture. The spark plugs provide the spark for this ignition. The pistons motion upwards and down, which leads to movements in the crankshaft and the wheel axles.

If the spark plugs are faulty, the ignition will fail, and the car volition terminate moving. This can cause the car to start for some second but misfire also much with a weak spark and then that the engine will die very soon.

7. Fuel Injector

The fuel is injected nether high pressure into the combustion chamber with the help of the fuel injectors. The fuel injectors' chore is to regulate, then the verbal needed corporeality of fuel will enter the combustion chamber.

If a fuel injector fails, it tin can cause the engine to run on fewer cylinders and also cause the fuel pressure to go depression if one is stuck open.

You can endeavour to feel on the fuel injectors with your hand while cranking to come across if they click. If they are not making any clicking sound, one of them might be faulty.

viii. Faulty Ignition Switch

If your ignition switch is damaged, you lot may commencement the automobile normally, and after a few seconds, the car will come to a complete stop. If your ignition switch is defective, you must bank check the switch contacts for wear.

The ignition switch is located behind the auto's ignition lock. In newer cars, it is most oftentimes incommunicable to replace the ignition switch itself; you have to replace the whole ignition lock.

9. Faulty EGR Valve

The EGR valve controls the exhausts that should be recirculated into the engine. If the EGR valve is stuck open up, it may enter likewise much air into the intake manifold.

This tin can cause the mixture to get too lean, which will also, therefore, cause the motorcar to start and and then dice afterwards a couple of seconds.

10. Engine Command Unit of measurement (ECU)

The ECU is a reckoner arrangement that controls various engine functions, including the fuel injection system. Since a vehicle needs fuel to motion, any ECU malfunction will cause the vehicle to come to a halt after starting.

The ECU controls the engine components via a series of sensors. Over time, the sensors go faulty and pass on erroneous information to the ECU. In this example, you must take your automobile to a car repair shop.
