Just wondering if they have a port on the 3.1L motor to test the fuel pressure. I have a friend with a 03 3.1L Grand Prix and I believe the fuel pump is on the way out. What I would like to do is first check the fuel pump relay and then of course test the fuel pressure.
Just wondering what would be the easiest way to hook up to this car, I'm not too familiar with these motors.
