My audi is having issues... I have spark & fuel..... at first i didnt have fuel so i changed the fuel filter.... now i have fuel, I am able to drive car for awhile and then all the sudden when i turn off the engine it wont start.... cranks and cranks but no start... any suggestions? 1993 Audi 90s

 

The fact that you changed the fuel filter to get fuel may indicate that your fuel pump is suspect. Check out the fuel pump.

 

Thanks i actually did pull the pump and found my negative wire going to it, it was frayed and barely attach.... kinda scared me i really dont want my car to catch fire. So i re wired it and put it back in, all seems to be working fine now. Thanks for the reply
