The in tank pump gets primed for a couple of secs by the ECM, it energized the FP relay. Check if your relay is working. Once it's running the oil pressure switch provides 12V even with a dead relay.

Listen if it clicks when you turn the key on. It should to prime pump. To try again, turn ign off wait about 15 secs and turn ign on again for another prime.
