I don't think upallnight will give up. If you can't get to the store to get pressure tester you can test for any flow at all at the fuel rail. you will need a helper to turn the key on and off so you can be under the hood and catch any fuel. Or, disconnect the line at the fuel filter so you can check it without the fuel filter in. Obviously, you have to be extremely careful and prepared for a potential fire.
