6.5 driver
So a buddy of mine has an either 06 or 07 Cummins and is having starting issues. He just had it in to the dealer and they put in a new intake heater and "cleaned" the injectors, didn't know they did that. Had to give him a jump today and it would only start after extended cranking and lots of wd40 and then it barely ran until , I assume, the air got forced out. My ? is what are the likely places for air intrusion?
