1993 Chevy S-10 6 cyl Four Wheel Drive Automatic 112k miles
fuel pump quit, or so I thought. Aftter replacing fuel pump and before reinstalling gas tank, I applied 12 volts to pump and heard it run. Then I checked again after I plugged the electrical connection together under the truck and turned on the ign but pump did not run. I unplugged connection and I do not have 12vdc at the plug. Fuse is good. I believe the fuse is labeled ECMB. I looked at a wiring diagram in a repair manuel and it said to check the fuel pump relay and the oil pressure switch. I cannot find either. Where are they located and what do they look like? Are we talking about the oil pressure sending unit that works the oil pressure gauge or lite:
have the same problem?
