According to my manual, the fuel pump is turned on by a signal from the EFI circuit opening relay which is controlled by the EFI main relay. The location of the circuit opening relay is behind the right kick panel on the trucks. When cranking the engine, there should be 12v at the FP terminal of the circuit opening relay. I attached a picture, but question if it will show up. Check the relay that I mentioned. Make sure there is 12v to the FP terminal when cranking.
Let me know what you find.
