    Default HELP 911 Cannot start truck

    Went to start my truck this AM and will not turn over.

    My code says P062F and P0633.

    tried to clear codes but will not.

    So I flashed my ECM and still have codes.

    If anyone knows how to fix this please help.


    Truck is LMM with no DPF and has not had the EMC re-call.

    Thanks
