get a wiring diagram and work backwards with your test light- that is an old truck, I wonder if it has an inertia kill switch?

Have you checked or substituted the fuel pump relay?

Thanks guys for the quick reply. It does have the inertia kill switch, it is good, checked continuity. I did replace the fuel pump relay, it was bad.
