    Gt40 no start (fuel)

    So first run of the year and I stalled out after 5 minutes of run time. I think I have a fuel issue and here's why...
    After 5 minutes the engine was stumbling for fuel, died, and would not restart.
    I started by changing the fuel filter (fcc), and it was dirty enough I was sure that was the problem.
    Now there is a complete no start with the fresh filter.
    Here's my caveman methodology for troubleshooting...
    I went to take the fcc apart again but when I drained it, nothing came out.
    So now I'm thinking fuel pump. I disconnected the main line to the fcc from the low pressure pump. When I turn the motor over with the disconnected hose, I expected fuel to shoot out but I never got a drop.
    Is it safe to say I have an issue with the low pressure pump?
    Is there a reset or fuse to check?

    Thanks for any help.

    By the way, when I turn the key one click I can hear the high pressure pump cycling/priming

        I've had similar issues on my 98 gt40 but if you prime it you should see fuel come out the hose..... Are u sure ur hearing it cycle when u turn the key. The relays also give problems but normally u wouldn't heAr them cycle when u turn the key.
