Guys I’m having an issue. I turn my keys on which powers my electric fuel pump the fuel pressure on my regulator goes right up to 47 where it’s set up when the pump is done cycling pressure at the regulator goes back to zero and I get a no start.
Any thoughts?
I’ve pulled both fuel filters and am getting great flow at the exit of each so no plugged filters.
