My truck dosnt want to start even though its been plugged in overnight.
Im getting a P2149 DTC gona try and diagionus it monday morning, It runs fine once started the first time of the day.

Is there something else I need to check besides the code trouble shooting?

p-2149 is for Fuel Injector Group 2 Supply Voltage Circuit.

Check your wire harnesses for any issues and maybe even ohm the injector solenoids to see if they are within tolerance. Other than that I'm thinking injector problems.

Cant explain this but in a bit of fustration I turned I turned my truck up to performance with my smarty Jr went and picked up 12000 lbs of wood and run the crap out of it, and the problem went away.

Im still gona check out the wiring and injector solinoids.

Is there anything in the fule system that could have been stuck causing the problem that a good hard run would have fixed?

I had same problem turned out to be injector. Ohm check injectors, the injector that has the highest resistance over 1 ohm is most likely the problem. Also ohm check wiring to the injector, careful when removing connector wiggling connector excessively will spread connections and cause problems. I use pocket screw driver and pull straight up.
