hey guys im having some problems with my fuel pump in my 97 s14. does anyone have a diagram for the connector this is located on the right side, underneath the dash in the passenger foot area? the one that the plug from the engine harness plugs in to?
thanks

also any other fuel pump wiring information would be great, i hate trying to read the fsm

The F3 plug? The FSM has a full schematic.

The fuel pump signal from the ECU is black/pink, goes through F3 across the dash to the fuel pump relay in the driver kick panel. Signal then goes to the pump through the black/yellow wire, going through the lower SMJ.

i think its the m63 plug? im horrible at understanding those schematics lol, thanks for the input. i have a 1jz in my car, and the wiring harness that came with it worked when i bought it. I took everything out to re-do it, and now the pump wont kick on. the fuel pump wire coming off of the ecu is not connected, which i think would definitely be a problem, but i labeled everything when i took it apart so it may not need to be used. As of right now, the black/pink wire is coming out of the m63 plug, and going into the engine bay? im trying to rule out possible errors and figure this thing out, every other part of the harness came together nicely so its gotta be something small.

The black/pink splits up, one side goes out the IACV-FICD I think, but the other leg does feed the fuel pump.

Ground that wire temporarily and see if your fuel pump works, it's a low current negative trigger from the ECU.

ok, do you mean on the back side of the plug? meaning, the black/pink wire runs from somewhere in the engine bay, and into the f3 plug. i should be grounding this on this side right? like plug the f3 in, and ground it so instead of going to the bay, its grounded? or do i have this backwards?
sry so confusing, im working with a mess here, and dont really have much to go off of. im about to bury myself in some fsms for the day....
