Fuel Pump Issue

If it was a short to ground it should burn a fuse or melt a wire. I would use a volt meter, go to walmart, harber freight, northern, radio shack, barrow, what ever. Test your voltage in, IE stock fuel pump power wire. Note the 3/S has a High/Low voltage regulator for the stock fuel pump power. Then make sure you have 0 Ohms to ground from the fuel pump ground terminal to the chassis or battery negative. Also check for ohms on the positive terminal of the fuel pump to ground, it should be open or no connection, all of this with the fuel pump sending unit plugged into the chassis harness. Good luck.

Going to test it tomorrow, if it turns out to be a ground issue, i'm going to drill though the sending unit, and tap in a M6-1.0 bolt and ground out that way though the top of the sending unit. Unless anyone else can think of a reason not to, my stock ground is so rusted i don't think much is making it though there, and this way i can get a good ground, and close up the whole made so that no gas leaks out.

Otherwise, i'll just grind down around all the holes on the sending unit and try several different grounding locations. I know last year i had an issue with the ground, buy my secondary straight to the battery was able to fix it. Even with that spot cleaned up it still doesn't seem to be doing the job any more.
