1994 Chevy S-10 fuel pump pressure

My info shows 55--61 psi.

does this 1994 chevy s-10 v-6 ,auto tranny have a fuel pump relay switch and if so where is located

There is an oil pressure switch in the fuel pump circuit. It is a redundant power supply to the pump, wired in parallel with the fuel pump relay, one should not effect the other. Voltage to the load side of relay and o/p switch comes from the same ecm B fuse, you need to be aware of that.
