He might be talking about the EBCM fuse... Electronic Braking Control Module (ABS).

Mine blew, pump continued to run, had to pull the fuse to get the pump to shut off. Truck kept running. Having the electric parts replaced now,t hough. 150 bucks sure beats 900 for a new unit.

So a fuse for the ABS could keep my FP from working?

well if it's pressurizing then it's getting power and working. Have you checked your fuel pressure at the rail? if no pressure maybe the hose that connects the fuel pump to the lid for the bucket (where the fuel lines are) failed? did you reuse that plastic piece from the factory or did you just use rubber FUEL INJECTED fuel line (must be for a fuel injected vehicle or it'll blow).

Either way if it's coming on and priming it's not an electronic problem, it's either the fuel line in the bucket or maybe even a bad fuel pressure regulator.

on edit:
I see that you reused that plastic hose, I didn't feel comfortable with fitting it to the walbro pump so we used high pressure fuel line (any auto part store) and the supplied clamps on Matt's truck.
