    Default 97 gmc fuel system problem

    Ok I have a 97 gmc 1500 with the 5.7.......The truck will not start unless you dump a little gas down the throttle body. Once the truck starts it is fine and will continue to start. If you let it sit awhile it wont start again. Would this be the spider being bad? I purchased the truck this way and it also had the intake gasket leaking. I am about to put it back together but want to solve this problem too.

    Default

    could be the pump it self or your fuel system is bleeding down while its setting i would suggest that you check and see how much pressure its putting out if its less then 58 psi at the schrader valve then your pumps dying 62 psi would be ideal if your system is bleeding down then check all your lines for small leaks and fix them as needed
