I just changed my bad fuel pump, also put a new
fuel filter, connected the new connector for it. The
pump isn't making noise an/or sound of it working.
Fuse looked fine. Any help?
Checked the fuel relay?
How would I check that?
Swap it with your ac or horn relay. They are the same.
Swapped them an still no function...
If you changed the wiring harness when you put new pump in,your issue may be the ground wire,s,there are two of them,body ground and ignition ground,swap them.
I have a black cable, purple cable, gray cable, an a black an white cable. Which would be which?
The black with white stripe,and plain black.
Switched them an still nothing. I think I might follow to wires to see if theres an open somewhere
How would I check if the fuel pump is getting power?
