Fuel pump check valve.

If you cracked the line at the fuel filter and no pressure spray of gas, you
either have a leaky check valve or leaky injectors (to echo some earlier

On the main Audifans page use the Google search engine on the words hot
start, hard start, or check valve, that will help you find some good info.

Good luck.
