    My bad , that's pretty important info to forget in a post. Lol

    88 gmc v1500 4x4 5.7 TBI
    the vehicle left me stranded yesterday. I returned to it this morning and it fired right up. In going to let it run for a while and see. It would appear my problem is the relay overheats.

    Okl, found a ground issue. Fixed it. Ran great all day. Let it sit a couple hours and went to start it. Nothing. Tried switching relays, nothing. Still no fuses blown and no fuel.

    Have you checked injector pulse? If you "checked" the fuel only by releasing pressure on the fuel rail, that's not thorough enough.
