    i had a gas leak at the fuel pump, and it sprayed all over the wire harness. when i replaced the fuel lines, i noticed that the plastic harness had actually dissolved from the gas being on it for so long. i think i know where the wires go, but i still can't get the pump to turn. i checked the fuel pump relay switch, and that is ok.

Hi Tom:
No make or model given so don't know type of ignition.
Would it be a big deal for you to do a compression test?
That might give a hint.

check again the fuel pump. check the resistance if too low. or unplug the pump and put a fuse again, if the fuse will not blow, then the pump went bad again.

Lets start at the beginning. Did anyone check fuel pressure before and after replacing the pump ?
Has anyone checked the fuel pressure regulator and the injector spider ? The 4.3w engine uses a spider with one injector that supplies all 6 cylinders. And it runs at 65psi or more.

How do you put the spark plug wires back in the correct order if you forgot the right order by not marking them???


The oil should be labeled 1-6. The spark plugs on the front of the engine ( radiator side) are from the passenger to the drivers side 1-3-5. The cylinders on the back side of th engine are from passenger to the drivers side 2-4-6. Put the worse from the cylinder to the corresponding number on the coils. If your coils are not labeled I would need to know the eight letter of your vin number to get you the correct coil numbers.

I have put 3 new fuel pumps in my 2002 cavalier and they all went bad with in about 4 months and i have put another new fuel pump in and now it wont start to pump fuel and i have power to the fuel pump....


Look at the connector in the left lower part of the dash. Like where your left foot would be while you are driving. You may need to move the carpet back a little and it's up off of the floor. there is large connector there I'm gonna say 16 or more pin connector. The fuel pump supply wire is in there, it is grey in color. Lots of times this wire is burn up in that connector. so the pump will work, but once it over heats the termanials it will die. Report back if that wiring is ok.
