Re: Cut wires on door - 1992 c1500

does your fuel pump only run for the prime when key turned ?

the oil pressure switch ( by distributor) is the switch that grounds the relay and allows the pump to continue to run.

you can by pass that by grounding, or use the tach feed wire to supply the ground.

the oil pressure switch is a nice fail safe if you ever loose oil pressure.
