I just replaced the fuel pump on my 98 silverado z71 and the harness that came with the new pumps wiring is different. the old harness has four wires colored gray on b, purple and white on a, two black,...


I may not be of much help.
According to autozone online, 96-98 model trucks should have - -
gray from relay to the pump
black / white ground for pump
pink - black for gauge ground
pink to gas gauge
You should be able to jumper the pump relay and look for a hot for the pump. You should have two grounds, I doubt it makes much difference which you use for the pump. And then you should have a hot for the gauge with the key on and the relay disconnected.

Hello tsundw.
Gray(positive from relay) and black (ground) are for fuel pump.
Purple and Orange are for your fuel level gauge.
That is a diagram for the gasoline engine.
Hope this helps you solve your problem.

The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.

Orange with black stripe should be the power wire (it should be the thickest wire in that bulk) also make sure that its NOT ground that's missing. That would be the black wire. Good luck
