The car quit while driving down the road. Sputtered and came to a stop. I replaced the fuel pump and the fuel filter. I could not blow though the old filter. The car wont start and stay running. It might sometimes idle, but not for long and when it does, its very rough. I had my wife turn the car over while I was in the trunk listening to the fuel pump and I did hear it run when turning over.
I would very much appreciate any ideas where to look for trouble. I am new to Audi and dont really know where to start. Thank you in advance.
