1 - there are only a few common ground points in our cars. Multiple circuits ground to a single point. If one has become corroded (or damaged - we're you in an accident?), it could effect multiple electronics. This could also be true of wiring bundles - if you were in an accident and a bundle was pinched it could short multiple sensors.
2 - your ecu is shot
I'm hoping for 1, but Occam's razor may be pointing at the second (especially if there are signs of physical damage to the casing)
If I were you, I'd roll her to the body shop and have her totaled. Get the cash and then decide how much its worth to sort this out. That's just my 2c though.

I pmd you. I have continuity to ground on the 5v and ground for the accelerator pedal. When I measure the 5v and ground wires on the harness (one end of the multi meter in each) I get .84v and 1.20v for each power and ground circuit. If I go from signal wire to ground I get about 4.5v from each harness. There is no continuity to ground on the signal wires.
Is this telling me there’s a short somewhere in the harness? Or is the dme providing no voltage to the pedal because it’s malfunctioning?
