Default Please Help! P0207 and P2146... Not the connectors!!!

OK guys.... here we go... so I've got a 2005 duramax that im about ready to burn to the ground.... it keeps throwing the P2146 and P0207 codes which will shut down a whole control group and cause it to run like a dang kabota tractor... so... heres what all I have tried.

ice picked #7, nothing happened.

Checked wiring and found no problems visually.

replaced every connector, nothing happened.

Replaced the FICM, nothing happened.

bought an injector and started swapping it around to all the injectors in the circuit... still nothing.

The code is really weird sometimes it will fire up and run 30 miles before it comes back and sometimes its instantly. Every time i get a ways away and i cant get the code to delete so i can get it home i can unplug the ficm and plug it back in and the code will clear....

somebody save me from committing insurance fraud on this paper weight....
