Fuse 27 relocation inefective.

So if I were to do this and the fuel pump kicks on, then the new FPDM is bad??

I believe that is correct

Do you have/using a Power Probe?

Did the bypass and still cranks, no start. I think the harness on the header wasn't the issue. Yes it was a problem, but I don't think those wires had anything to do with the fuel pump. Also, the fuel gauge reads zero. I know it's got gas in it.

Yes, fuse relocation is hot, but only pin 1 has power at the fuel pump control module. Not sure if this is correct or not. Tank is still half out so will check power at the pump next.
This has turned into a major pain in my ass.

More spit ballin’ here, but do you have any codes or notifications in reference to the Restraint Control Module (RCM) or the SRS, which will cut fuel if it senses a crash? I know long shot.

Check engine light isn't lit but will scan it anyway.

Looking in the manual, it shows DTC fault B11D8:12 or B11D8:14 in memory. The air bag warning will not be illuminated.

Short to voltage, short to ground, open circuit

With the harness the way it was burnt, being optimistic, as the signal to the FPCM from the PCM could have set that off due to the RCM sensing the short. Fingers crossed

In the mustang world the FPCM reset button is located in the trunk by the tail light behide the trunk material. I know not very helpful and I'm not sure if a truck would have a reset button located somewhere.

Zero codes. Going to drop the tank again and check my NEW fuel pump. Possibly I installed a bad one. Last attempt before throwing in the towel. Hate to pay several hundred @Ford when I "should" be able to fix it myself. Jumping the module and not hearing the pump, plus 0 gas on the Guage tells me it's at the tank. But who knows.

Partially... It means the signal from the FPDM and the BCM is not good. But yes, the fuel pump will run so that eliminates the fuel pump as the problem.
