I have a 1985 VW. cabriolet. runs for by 4 seconds and a quits every time
Check fuel filter?
If not filter check pump.
I put new fuel pumps.the one in the gas tank and the other one that goes out. New filter.cold start valve check. Fuel injectors work
The question is,after that four second,s of running and cutting off,which one is not working, fuel or fire?You may need to check fuel pressure and see if it drop,s leading you to fuel problem,if pressure hold,s look for firing problem such as coil.
All so check your ditsributor for bad rotor or cap.
hear is a good question is this car got a regular carburetor or the fuel injection system that's mounted on top of the air box? cause i can almost garentie its that stupid thing it tends to dry out if your car sits for over a month. i had that issue with my 1985 audi 5000
