Question about 1997 GMC Sonoma
It really helps if you post which engine you have and the 8th VIN digit. I ASSUME its a V6??? You should have 12 volts for 2 seconds on the gray wire (at the pump) when you turn the key on, If not, check the ECM/BATT fuse #9 20 amps, in the dash fuse panel. IF you do have power, then the relay is working and that is ok, If it does have power to the gray wire, then shuts off after 2 seconds thats normal. NOW while its running the fuel pump gets power THROUGH the OIL PRESSURE SWITCH. So get it running with your test wire, then disconnect your test wire. If it stalls out, then the oil pressure switch is either bad or disconnected.
