Car stalling Sign In

My daughter has a 1999 volkswagon beattle that stalls frequently, and we have no idea why. some days it runs fine. When it does stall, she pulls off to the side and waits, and it eventually starts back up and runs fine, it has been doing this for awhile. We just changed the fuel filter thinking that might be the problem but no. Just don't understand why this is happening, anyone have a solution for this.
The engine is a 2.0, no turbo, manual trans.
Thanks, Ray

You don't just get magical solutions without testing anything. That would take a crystal ball.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Also, does this have any trouble codes stored in the engine controller? If so, what are the numbers?

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
