Truck Repair/fault code 332


Hi, I have a prime mover truck with n-14 engine . when I runned a vehicle scanning it turns out that I have a fault code 332. What are the basic troubleshooting for this problem. Thanks.

Code 332 is your getting no current to the injectors. First thing I would do is check the injector harness back to the computer and also check the wires inside the head. if you don't see any problems I would ohm them out to make sure. If everything goes good there and you know you have power going to the ecm then more then likely the ecm is fried.
