Engine Mechanical problem
1999 Audi Quattro 4 cyl All Wheel Drive Manual 130000 miles
Strange problem. My car starts without a problem when the car is cold, but if it's been running for a little while (usually more than 30 minutes) and the engine is warmed up, it has a hard time restarting after I turn off the engine (stopping at a gas station is always a hassle).
The engine eventually catches (very slow, gradual catch), but it just cranks and cranks and cranks sometimes for 15-20 seconds before that happens.
Need to do a fuel pressure test. See if it is bleeding down due to a bad regulator or pump. Have the PCM (computer) scanned for codes, Autozone will do it for free. If the PCM sees a problem it will store a code that will help in diagnosing the problem, get back with the exact codes.
