I think my fuel pump has give up!. Do to the extensive work on replacing fuel pump. I wanted more advice. I have good spark so I checked the fuel pressure on the fuel rail. I only have 10 pounds and should be over 40. I have good voltage at the fuel pump relay although I have not changed the relay. I feel with the car mileage, ( We have put 110K on care since we bought it ) the pump is gone. I did pull the fuel filter, turned the ignition on and it does pump for 2 seconds but seams weak. my filter is alright. Will this care not run at all on 10 pounds??? Is there a chance that the regulator is bad?? It looks to me that the regulator is part of the fuel rail and not replaceable unles you replace the whole rail.

It might be. I have a 95 Trans Am and the pump went out at 100k, but when it quit it quit all the way.
