Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

The fuse for the fuel pump is pretty much the toggle switch between tanks, if that goes out, you will not have either tank.. IF you had an accident, there is a kill switch somewhere behind the dash on that truck that disables the fuel pump and must be reset.

There are 2 fuses and a relay involved in this circuit but the lines that run power to the pump run partially exposed under the vehicle as well. Check the Interior Fuse, check the Fuse in the box under the hood and check to make sure you have voltage at the fuse under the hood. If these are good check for voltage on the wires going to the fuel pump at the fuel pump itself. You can do this with a multimeter and thumb tack. Use the thumb tack to puncture the insulation in the wires and test for voltage. If you don't have voltage there, start working your way back 12" at a time until you find the point where you have voltage to isolate the area of the break.
