fuel pump,
jump fuel pump relay and see if you can hear it running, if not, hit tank with a deadblow hammer and see if it goes, at least for a bit.

When you first turn your rig on, the fuel pump should run for about 3 seconds. Same when you turn it off. +1 for jumping it at the relay under the hood, but this can be kind of a PITA. Good luck, dude.
