No power to the fuel pump relay circuit

[536487]

Hello all, I just purchased a 1992 Lumina and i have recently found out that there is a problem with power being supplied to the fuel pump relay. I contacted the prior owner and he had stated that there is something that is blowing out the fuse. I can only assume that this is a main fuse of some sort. Does anyone have any Idea as to what could be causing this? My fear is that it is the main harness.

Thanks

I have the same problem. I replaced the fuel pump, checked the relay and fuse. They are ok. There's no power to the relay. Could there a problem w/ the Engine Control Module or the wire powering the relay?

Check your fuseable links. You may have one blown that supplies power to the relay. The fuseable links are attached at the battery post near the battery.

Ok, I'll check that but I have power to the starter and almost everything. There's no power to the org wire before the 20a pump fuses. Could I just jumper 12volts to this wire? Does the fuel pump use 12v or is it less? I search the web and could not find the voltage spec for the fuel pump. If I know this voltage I could just jumper and my problem would be solved.

Fuseable links carry primary power independant of the battery cable to various components. Look for burned or discolored sections, or feel for absence of wire inside insulator. I would be careful supplying 12V to anything involved with the fuel pump, unless you are very sure you are right. (fingers in ears, moving away quickly)
