I am MSD81. But it doesn't always prime the pump. In fact now that I am thinking about it, I don't think it has primed since I had a issue with one of my Walbro 450's drawing to much amps. I wonder if it burnt out..

Well at least you have some direction now.

Does your pump prime every time? I thought it doesn't prime if the LPFP sensor reads 70psi.
