5 Causes of a Car Starts then Dies Immediately

When you attempt to start your car, you normally assume it is going to start without any problems. You’ll hear the engine turning and everything will seem fine. However, there may come a point in time when your car will start but then die almost immediately afterward.

This will aggravate you a lot because it will seem like your car should be working since you got it to start first. So naturally, you’ll repeatedly keep attempting to start your vehicle until it doesn’t die.

Unfortunately, you won’t have any success at doing this once it dies the first time. The only thing you can do is figure out what happened and then fix the problem.

5 Common Causes of a Car Starts then Dies

There are lots of reasons as to why your car would start and then stop immediately. After you’ve tried to start your vehicle a couple of times with this problem occurring, you should avoid trying again.

You don’t want to risk making the cause of the problem any worse. Speaking of which, below are the top 5 causes of a car dying immediately after you start it up.

1) Fuel Pump Leak

If there is any kind of leak in your fuel pump or fuel injection system for that matter, it will create problems for the internal combustion process. The engine requires the right amount of air and fuel to mix together for ignition.

But if there is a fuel leak somewhere, then the proper amount of fuel won’t be able to make it to the combustion chamber. This might cause the engine to still start, but it won’t be able to keep it running. That is why it will die almost immediately after it starts.

2) Fuel Injection Sensor Issue

The fuel injector requires a certain amount of pressure so that it can inject the right amount of fuel into the internal combustion chamber. The engine control unit communicates with the fuel injector through the sensor that is attached to it.

The sensor keeps track of the amount of pressure in the fuel injector and then transmits this information to the engine control unit. From there, this computer modifies the pressure accordingly.

However, if there is a problem or issue with the fuel injector sensor, the engine will not receive the right amount of fuel for a proper combustion. This could lead to a starting car that dies right away.

3) Ignition Issue

The ignition system is responsible for generating the spark that ignites the mixture of air and fuel in the internal combustion chamber.

If you were to have any issues in your ignition system, like with the spark plugs or even the car battery, then the spark might not be sufficient enough to create a full ignition in the chamber. This could cause the car to die if it does start up at all.

4) Bad Carburetor

The carburetor is a very important component of the internal combustion process. In fact, it is responsible for properly adjusting the ratio of air and fuel so that the combustion can be successful in the engine.

So, if you have a bad carburetor that is malfunctioning for some reason, it will likely throw off the ratio of air and fuel. Then your engine’s combustion will be ruined.

5) Engine Control Unit Issue

The engine control unit is a computer that is susceptible to glitches and errors like any other piece of electronic equipment. But it is even worse for the engine control unit to have this issue because it manages virtually all the electronic components and sensors of your vehicle.

One potential problem that could arise is the inability to control the fuel injection system correctly. This might cause problems keeping the car running after you start it up.
