Hello, 4.3 vin Z, my details shows, under the hood, firewall, driver side of brake booster. When in doubt about the relay, look in ~ the cable colors in ~ the connector, DK green/white, gray, orange, black/ white.The info also shows an oil pressure switch in the fuel pump circuit. Once you crank it sufficient to bring up oil pressure and also the switch closes, the pump have to run, also without the relay. The info likewise shows a prime connector, about the center of the firewall, gray wire with connector, if you use an inline fuse ~ above a jumper and also run B+ come the connector, the pump must run, friend don"t have to use the key.

1993 Chevy T10 4X4 4 door Blazer w/4.3L Vortec engine w/W code in vin #.I parked the truck one day and it wouldn’t begin the following day. Ns noticed that the fuel pump wasn’t making any kind of sound as soon as I turning on the ignition key. So ns disconnected the wiring plug at the behind of the tank and also connected 12 volts from another source (trailer hitch light plug) to the fuel pump. Still, there was no sound native the fuel pump. I then purchase a new after market fuel pump and also tested come make certain it work and it was fine. After I inserted the pump and reinstalled the pump, still didn’t work. Twin checked the wires making sure they where all connected. Re-tested the old fuel pump top top the battery and also it tho didn’t work. Now, I need to think it shed out the fuel relay. Ns tested the cable to the tank through my OHM meter and there is just 8.46 volt going to the fuel pump. My question is can you aid me whereby the fuel pump is located and also if girlfriend have one more suggestion the might help me v this difficulty would surely be appreciated.Thank you’Brian
