89 CUTLASS NO FUEL AT THE INJECTOR RAIL
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!

RE: 89 CUTLASS NO FUEL AT THE INJECTOR RAIL
Is there enough gas in the tank? If so, I think that the fuel pump on that model is hooked to the sender assembly by a short piece of hose and two clamps. I have seen this connection come apart and; although the pump is running, it is putting the gas right back into the tank. I have also seen the line get kinked shut while putting the gas tank back up in place. And there's the off chance that you got a bad gas filter or you somehow installed it backwards.

That's all that I can come up with at the moment. Please let us know if any of that helped.

Thanks for using the forum,

Good input. I did added the lawnmower gas to the tank just to be sure and verified that the fulel filter was installed with the direction of flow correct. I'll drop the tank again, and let you know what I find. Thanks again for your help.

Before going too far into the job I'd double check for power and ground back at that connector near the fuel tank (should be there for 2-3 seconds after the key is turned on).... AND.... if it's an aftermarket pump (Delphi?) with the "do it yourself" universal harness I'd also double check to see if you got that correct.

If you did a "pump only" without the complete sending unit, did you remember to plug the pump in during the swap out?

BTW, one last dumb question.... did it run before you changed the pump?
