I checked my IPR voltage again today and it was 12 volts with key on, so I put the pigtail back on, and tried to start the truck and it started. I was shocked.
BUT, then it died. But my high pressure fuel pump is leaking a bunch of fuel and I think it got air in the system, so it won't run again. Where can I get the O ring that goes in the high pressure fuel pump by the little screen? I called Ford and they don't even list it.
I hope it is just air getting in the system now.
Where the high pressure fuel pump hooks up to the fuel bowl, there is a small screen that fits snugly into the fuel bowl, but supposedly it should have an o-ring. I have a big leak there and I think it is putting air into the system.

Right above where you have the arrow for the fuel filter restrictor, you will see two bolts that hold on the regulator. When you remove those two bolts there is a little screen in there that protrudes and it fits into the fuel bowl. That is where it is leaking
