I would get a light tester and go backwards from the pump following the wires and find where you have a power loss.

may be a connector at the pump..... i would take them (at both pumps) and clean them then apply some dilectric greese

Check your fuses and look for any wires that might have been chewed by a mouse under the hood.

Have you checked for spark?

i dont think it would of been a mouse chewing wires when i was driveing it when the problem started

check the ground wire at the battery. there should be a large one that goes to the frame and then the block and a smaller one that has a connector on it that goes into the harness.
the smaller one is the ground for the ecm. if its messed up, in any way, you won't get fuel or injector pulses.

Good point, I had to replace that on my choptop cuz it corroded to junk, but the truck still ran (somehow) when I replaced it.



And if a mouse chewed on a wire, it could have been a bump that shorted it to the frame or something.... I have an ongoing feud with the local mouse population...
