Some of these aftertreatment faults have a hard time resetting themselves. You could try re-calibrating the ECM. After that you can chase the "no cranking" complaint. Make sure keyswitch voltage is going to the starter, make sure the ecm operating state isn't showing something like 'starter lockout', see if the ECM throws any faults after a reflash.
