I have a 2000 Audi a8 with the 4.2 V8. I was driving along last week and everything was fine and suddenly I lost power and the RPMs went to idle, when I pushed onthe has pedal, the RPMs would drop, and I had no choice but to pull over. When I stopped, the idle became rough, and the engine began to sputter then died. The engine would try to start to no avail. I diagnosed the problem as a bad fuel pump and replaced it. After the new pump was in the car started right up and ran fine for a few minutes, but then it started sputtering and died again, and won't start again. Shortly before the the problem originally occurred the check engine light came and I ran the codes and it came up as a bad mass airflow sensor, and temp sensor if I remember correctly, but I was very busy and didn't have time to change them. Could the problem be the sensors?

I always have to crank, stop, then crank again to cold start it and it always starts. If it has run with in 15 min, it will start right up. If it sits off for more than say 1/2 hr, I have to crank (say 5-6secs) stop, then crank again and it will always start up. Its like a valve is slowly leaking allowing the gas to leak back into the tank, and I have to wait for the fuel pump to pump it back up to the fuel injectors. Is there such a valve? I have checked and can't find any external gas leaks. This problem has gone on for a year. I used to cold start right up in 1-2secs every time. Can someone help me?

I have not had a problem with my car starting until freezing temp's. will starter fluid possibly work?

The hissing stops momentarily when turning the steering wheel. The sound began after I had a used engine installed but the mechanic can't figure it out.
