89 Olds Cutlass Ciera 2.8L 103,688 miles
I've always been able to hear the fuel pump prime when the key is in the on position. But no sign of fuel at the injector rail. Now I've changed the fuel pump, fuel filter, fuel pump relay, fuel injector pressure regulator, oil pressure sensor, crankshaft position sensor. I've cleaned the mass air flow valve and most of the grounding connections. I've ohmed the injectors and verified power to the injectors while cranking the engine. PLEASE HELP!

Well, now that you have thrown every part you can think of at it, maybe it's time to do somew testing like the fuel pressure and power arriving at the pump.

If I can hear it prime, then the pump it must have power at least through the prime circuit. With no fuel at the rail, I can still hear light air escape, but it's nothing that would be measurable with a gauge. Maybe 1 to 2 psi.

You seem to have your own agenda and i can't seem to get you to do what I ask so you'll have to find someone else.
