97 starting problem

Helping a neighbor try to get a 97 started that a guy dropped off at his shop. It has new GPR, Plugs are working. It will start cold with a shot of either, BUT after warm, it will start. It seems as if its a fuel problem, but there is no white smoke while cranking. Once its running, it seems to run OK. It has about 45# fuel pressure at the schrader valve while idleing. Any thoughts?? Oil level is good, etc. One other question, after it runs and you shut it ff, the fuel pressure drops off to nothing on the gauge. Is that normal? We checked my truck, and there was nothing when we hooked it up, it had 60# when idleing, and stayed up after engine off. Thanks

It might also be an IPR problem with a fuel pump or fuel related problem, even if pump does not hold any pressure, you should get a little smoke when cranking! Also check the blue(well should be blue) fuel hoses going to fuel filter bowl from pump maybe one of them is leaking in the valley.
