Then you don't have power to fuel pump from fuel pump relay.

But if your turning key on and off? Sometimes it will not prime until off for awhile, all ECM/PCM have different timers but 30 seconds should cover them all.

Does your fuel pump relay have an extra Red wire hanging from it with a plug on the end? If so you can run 12 volt Batt power to it to keep fuel pump on while testing.
