If you have both power & ground to the pump, then that just leaves the pump.

Bought a multimeter, it does not look like I am getting any reading for the ground???

What now?

Hope I did this right, I put the negative part of the multimeter on the purple wire of the fuel pump connector, I checked the wht/blk ground on the plug and it read around 5 volts..... the all blk wire did not read.....

Now, will the gry power wire just read for the 3 or 4 seconds after the key is turned on? Or would that be constant? IF it is supposed to be constant, I am not getting a read on it.....

what to do now????

Ok... tried again, checked the gry wire when the key is turned, 12volts

Blk/Wht wire= 12 volts

Black wire= 5 volts

Purple wire= 5 volts

Sorry for posting back to back.....

What to do now????????????????????????
