Thank you R.E.D

3 ish volts on a fuel shutoff solenoid?

that statement puzzles me 

I don’t think this uses some kind of “reference” signal. Solenoids work on 12volts  

so where that Deutch connector is, Is it on a pigtail that comes out of the rear cover?

Turn the key on, and wiggle the pigtail where it comes out of the cover and listen for a click  

I had to pull that rear cover off, and the wires inside the cover were not making good contact. Needed to solder the wires that go to the shutoff solenoid.
Nothing falls when cover is removed.

Im thinking we could even start the truck with it off.
