Is using a ScanTool OBD scanner to read fuel rail pressure a good alternative to the mechanical gauge? I was running some tests today with it and it appears I can read fuel pressure through the scanner with the ignition ON but the car not started. Is 30 psi the expected pressure with the pump engaged before the car is running?
I'm thinking I just keep doing this until I see another no-start scenario and see if I see a corresponding drop in fuel pressure. Since the problem is random, I'd really love to not have to pop my hood and connect a gauge every time I start the car.
After watching a few videos on fuel pump replacement I'm really hoping this isn't my problem. A tad bit more involved than the 240 :\
