TBC is Trailer Brake Controller. And guess where that is, In the PCM. Now looking on other forums. Guys had this issue and a no start due to either, bad fuses or relay or wiped out pcm memory (fixed by reflashing it at the dealer) or bad grounds or crapped out pcm.
So what im thinking now and thinking back since the beggining this may be your issue. i know you checked those fuses and relays but id check again and check all ground including the pcm, if nothing comes up, then your best bet to bring it to the dealer for them to look at and atleast get them to reflash the pcm, if that comes negative, they may have to replace it.
This is a very rare problem, i would of never thought of it.

Ive done a pcm swap before to prove a point to somebody for some odd reason, its been awhile. But It started no problem but multiple codes appeared though. I swap a 06 pcm for a 03, and they had some different maps in them but didnt stop it from starting the truck.
So you can definitly find a used pcm but i recommend that you get ford to re-flash it and download the original maps of this specific year. it shouldnt cost a whole lot.
Testing the relay isnt to hard. Just look up some youtube videos, theres alot of them.

A further development.....i found out that the turbo drain tube is leaking. It took a bunch more cranking before the oil pressure gauge would read anything again. So thats an issue and ive pulled the turbo back off to try again with the drain tube. Another issue is the oil tube inside the filter housing broke. So all the oil is just draining back into the motor when i stop cranking. Gotta get that fixed now too. Relays all seem fine. So once the oil system is finnally sealed, if it doesnt fire up its going to get scanned. Im tired of tossing parts at blindly.
