Checked the wiring as @diesellibrarian suggested and now we have power back to the pump (even though I didn't fix anything...)
Checking voltage to the pump via the exterior access panel (driverside quarter panel rust hole) I'm seeing 8v at startup and when the throttle is brought up off idle it increases to 11v. Looks like I need to recheck everything between the relay (it's a constant 11.9v).
Somebody has been at the fuel pump circuit with shoddy crimp connectors as I've since found several inline fuses added. Most annoyingly this one,
which I didn't see until after we took the thing for a drive (note it was unhooked like this when I got all my earlier mentioned voltage readings and drove the truck around).
The truck will now die at random times when driving and won't restart until I let it sit a minute while whispering sweet promises of a rebuilt suspension and new(er) tires. Something it didn't do when powering the pump via a jump pack. I'm suspecting that it's linked to the inconsistent fuel pump voltage and possibly still yet unidentified wiring gremlins).
