In my quest to shorten my cranking time Ive uncovered another issue. When I turn the key, the fuel pressure shoots up to about 40psi then falls to about 10psi and stays there. Then while running the fuel pressure is about 30psi but will jump to 40 psi with the regulator unplugged. I tested the fpr with the car off and it holds vacuum. Does it sound like the check valve in the fuel pump? If so its a shame because it is still strong. Maybe a leaky injector? I did smell some raw fuel around the passenger side valve cover when I cycled the key however that could just be from the shrader valve since my fuel pressure tester was still installed.
