FAQ 96

Question: Here is my dilema I feel that there may or may not be a short in the wiring somewhere in the car you tell me. I was able to start the car let it run and it would run for about 15-20 minutes then just cut out. Originally I thought maybe the generator was bad so I converted over to an alternator but the problem still exists. Is it possible that there is a short that is causing this or is it the engine itself? I know that it can't possibly be a fuel flow peoblem

because we have installed a clear fuel filter and electric fuel pump. I'm really frustrated cause I can't drive it I can only start it and let it idle! thanx appreciate any help you can provide.

Answer: My first guess would be coil. When the spark coil is going bad it often will work cold, but stops working when it heats up a little.

If the fuel is fine for 15 minutes, it'll almost always be fine for hours.

You need John Muirs idiot's guide: "How to Keep Your Volkswagen Alive". This great book tells how to diagnose a 'not running' problem. It has step by step procedures to diagnose spark and fuel problems.
