I have a XDP Fuel Pressure Regulator and a Fuel Bowl Delete. I noticed that my FASS Fuel Plat Fuel pumps dont make the loud priming noise when I turn my truck on ACC. However, it still starts up and Runs. And I just noticed that I have 0 psi on my Fuel Pressure Regulator.

What is going on? Fuses seem to be good and not burnt out. What else should I check?
