1994 GMC Sierra fuel pump relay

According to my info, the only fuse I saw was the crank fuse for the control side of the pump relay, once the key returns to the run position, the relay is no longer energized, then the pump should get voltage from the oil pressure switch in the pump circuit. If you want to check voltage for the crank fuse, the key has to be in the crank position. The relay only supplies voltage to the pump during crank then the o/p switch takes over.

If you do testing at the o/p switch, once you crank enough to bring up oil pressure, the orange is hot all the time, the gray goes hot when the switch closes.
