Stupid truck!!! Crazy no start issue!

Here we go... Bought a 05 F250 with 150k miles not running. It used to have a plow on it at some point and the only remnants are the large wires going from the front to the back, weird headlight wiring, and lots of rust.
Anyways, I tested it before purchase with my AE. FICM was 48v constantly, would crank over and IPR increased like it should, ICP did not build pressure. So, Brought it home.

Did the air test. Closed the IPR with AE, massive leak at hpop behind the gear. Bought and installed a replacement hpop and ipr. Still no start. Changed the starter because it was starting to drag. Still no start. Gave up on it for the evening.

Next morning, went to try a start with nothing hooked up to the truck and it would do nothing. No cranking, only a battery and airbag light would show on the dash, no noises when the key is turned on. Puzzled, I go grab the laptop and as soon as I plug in the AE dongle, everything lights up and it will turn over. Unplug the AE from the DLC and it is dead again. Plug it back in and it appears normal. Ran some tests and 2358 injectors failed. There were even codes for amismatched vin. Puzzled... I am assuming it is some sort of electrical short, wire unplugged, chafing issue. But, where to start??

I would start at your batteries and work your way back. Mine did something similar a while back and I traced it to one of the injector wires under the degas bottle. It was rubbed bare and shorting out and gave me a no start issue.
Someone posted on here that this problem usually occurs when the ground on the right side of the engine block comes loose or off.

Thanks for the reply Ryan. I just needed a lil boost I guess. We bought this truck not running for CHEAP. I know it is electrical and that I just have to dig in it. At least I have a couple of spots to check first before I start looking at every inch of wiring.

A little update....

After a bunch of pinout tests, I cleaned 5 ground connections (one by abs module, one on firewall outboard of degas bottle, one on intake by the ficm, strap on passenger side above hvac box, one by emergency brake). Ended up disassembling the blue plug for the cluster and one wire at a time, I removed them and tightened up the hole so it made a tighter connection when plugged into the cluster.

The thing fired up eventually. Oil pressure registers on the dash, ICP build rather quickly now. The issue I am having right now is that it won't idle. If I press the gas a bit, it will run great. Sounds good, revs up fine. As soon as it approaches idle speed, it acts like you turn the key off. A little bit more troubleshooting and it should be up and running.

It is FIXED! Cam position sensor swapped out and it idles great now. Crazy that it would run with the bad one but not idle. Go figure..
