this is a dumb question but has your dealer plugged into the sled to read all stored codes? also i remember reading about someone having a broken wire to the fuel pump i believe it was under the seat near the pump. Also there is known wire rub low on the front of the engine on clutch side on a casting nub near bottom of engine my wire harness was starting to rub on there when i looked. Sorry i am not more help. mine wouldn't start once either at 20 below, code 43 also. left it over night and it started up the next day, never did it since.

if you have fuel line freezeup or the pump and /or injectors freeze id bet this could cause the code..if the pump cant deliver the fuel from restriction or from a faulty injector...it would throw the code...or if an injector somehow came unplugged..
