    Its on my 6.2L. Its not the GP. I think it is taking time to get fuel. It sits for a while and it like it drains back or something like that.

    thanks mike

    I would suspect a leak of some type. Normally fuel stays in the line. If the fuel moves back down, then air is getting in the fuel line somehow.

    Just a suggestion, but you will get better results in the Diesel forum.

    well the only thing i can say is
    1 if you got air in the line it would be a bit*h to start if you could do it at all that is a diesel trate
    2 a electric pump can start slow or catitave if it not a diesel pump ( the foam - air in diesel )
    3 is the cam on the diesel pump corect (the pump on the moter that feeds each pisten)

    i did not get my hooked on fonex yet /forums/images/graemlins/rotfl.gif

    sorry i could not help more
