Bought a new fuel pump for my 1998 gmc sierra and the connector from the old fuel pump is two connectors one 3 prong flat and one 4 prong square and the new pump has the same flat 3 prong connector, but it has a 4 prong flat connector instead of it being square got a pigtail with new pump if i splice with new connector what wires go where
If the connectors are wrong, it's the WRONG pump. Return it

SOURCE: M already changed the fuel pump (module) but ,the
the one with the thin white wire goes to the thin black. The thick black is the pump ground
Testimonial: "Good answer. Thamks a lot!!!!!!!"
SOURCE: The truck was dying sometimes. We changed the fuel
i dont believe there is a fuel cutoff switch on that yr but you might want to check the pump take it out and wire it straight to the battery for a few seconds if it doesnt kick on and stay on then return the fuel pump... if it kicks on and stays on then you might want to consider a new sending unit as well as the pump it doesnt cost that much more and then you wont have that worry later down the road
SOURCE: I have a 1995 gmc
You might find the pieces of harness at a salvage yard. Also you can use wire connectors available at ant auto store. Use a good crimping tool and wrap the splices with electrical tape.
SOURCE: 97 GMC Jimmy fuel pump won't come on
Should be a green-yellow wire from the relay to the pump. The pump is grounded thru a black wire in the harness.
The wire from the relay should be hot when the relay is engaged by the computer or if you jumper it.
