Challenger Posted March 25, 2013 Share Posted March 25, 2013 Did you have VMAC III software? If so go into service, monitor parameters and click on boxes eecu power and vecu power and check to see if both ecu's have power. If no power check your fuses. Or plug in an another VECU. Use a test vecu or a sister truck vecu. The vecu is located on in front of the passager seat behind the kick panel. Basically behind the metal plate where your feet would rest. They are easy to remove and install. If the truck starts with a different VECU replace the vecu. You can do the samething with the eecu just to make sure its not bad.
