To test the hpfp
If he has a good scanner he can open the volume control valve in the actuation settings and command the valves inside the pump itself to prime itself..
KOEO cycle 3 times to prime the pump, command it to close (volume control valve)
Command the pressure control valve open and it will draw in the fuel from the VCV
Command that to normal state.
Fire it up hit the gas and it should stay running
I rebuilt my engine
Had air keeping it from running for 2 days straight.
Maybe one of those valves is stuck open, allowing for return.

Ps the engine running backwards gag was more of a funny comment. On an open forum where anyone can say ANYTHING THEYD LIKE.
It was a joke
To get you to Fn laugh and not be so stressed about a crap truck you canít figure out.
Didnt think youíd take me seriously.

Removed module and vac/PSI tested. Passed. Took it apart and didn't find anything damning but ordered new anyway

Makes sense, glad you seem to have found it. Are they factory filters or some sort of after market? Maybe the o ring isnt sealing in the bottom really good?

Yeah that crazy man, kinda went with my theory of a drain back issue, cant say ive ever seen a pump do that. Seen a few have issues with suction lines sucking air, but never one like this...

It very well could have been draining back. The flapper on inside of the module was ok when I took it apart. We'll see.

This truck goes into the learning category
