there has to be a reason why you would be testing the fuel pressure under the hood to begin with. If you have a defective pump or a pump that is going out on you, there really is no way to find out ( other than your motor struggling when accelerating because the electronics are simply failing. I don't know much about gm ( I usually buy Ford or VW) but I know enough about fuel pumps, that the fuel pressure has to be consistent to get down the road based on the demand of the gas pedal. I'd like to help you with this, but really there has to be a reason why you even think of this. you have to buy a fuel pump test kit for your valve anyhow. i need more information, please
