Fuel pump problems again.

Ok I have replaced the Fuel Pump (rear tank), fuel selector switch in the dash, fuel pump relay, and the 20 AMP Maxi fuse.

Also the ground/wiring is correct. Triple checked.

The front pump works fine, but the back won't come on.

Help!

You will need to verify that you have power back there when that pump is selected, you would jump pins 2 to 6, I believe on the test plug...be careful not to short out, maybe use a test light and a clean ground

I did the power test where it actually hooks up the fuel pump, no power, which is where I thought the selector switch had bad contacts for the rear.

So I'm at a loss?
