I don't know what you mean because the pump black power and white ground would be much thicker then the fuel gauge sending unit black power and white return. The fact there may be an addtional chassis ground should not be confusing. All you have to do is connect one wire at a time, just as they are now. I don't see how you could get them mixed up? Don't they go to a keyed plug?

Fuel pump wire color


The gray wire goes from the pump relay to the pump. The black white wire is the ground for the pump. The purple is for the gauge on the dash and the black is ground for the sending unit. I don't list a white wire being used.
If the colors on the truck don't match the tank, you'll have to test them to verify each circuit.

I need to replace the fuel pump and the parts house sells it with wiring. Do you have a diagram of how to run the wiring?? It is for a 2000 chevy blazer. Need it asap.


Grey is the power to the fuel pump.
Purple is the power to the fuel level sensor.
One black wire should go to the frame (fuel pump ground).
The other black wire should go to a connector and back to the fuel guage.

Fuel gauge problem not working


its more likely the sending unit resistor inside the tank. sometimes you can replace just the float resistor with another working used one but most new ones come only as the complete unit

Were can I find the fuel pump collison switch on my 2000 chevy blazer? I quit a week ago started the next morning, quit again yesterday, pump not running relay checks out, jumper pump does not run?


You do not have a switch like a ford. If you have power for three seconds when key switched on and no fuel pressure you will need a pump. I think its the gray wire on yours. Test at the pump connector

We are replacing the fuel filter in a 98 pontiac transport. The new wiring harness came with a purple, grey & 2 Black wires. The OE harness comes with purple, grey , black and a white/black. How do you...


Assuming you mean replacing the fuel PUMP, the 2 wires are different guages. Connect the lighter wire to the lighter wire and the heavier wire to the heavier wire. If the new harness uses both the same size wires, the heavier wire on the vehicle side (solid black) is for the fuel pump ground. Lighter wire is for fuel guage sending unit.

did you check power and ground at the fuel pump connector?there should be power at two wires at the connector,one should have constant power with the key on and thats for your fuel gage,the other power wire should have it only when cranking or for about 3-5 seconds when the key is turned on,check both of those first and that will let you know that everything is fine all the way forward of that connector,also did u replace just the pump or the whole sending unit?if you just replaced the pump the connector that runs fron the sending unit to the actual pump itself inside the tank also goes bad on this setup too,look for brown or burn marks on the inside of the sending unit where this connector hooks uo,hope this helps
