BCM module changed no start and check engine light

Recommended Posts

Had done the Byepass on the truck a while back, had a friend at the Dealer check it for something else but he found error codes in the BCM which he went ahead and cleared them! To our surprise the Truck did not want to Start, he checked it and said that the BCM was bad. Found one and he installed it, he could not program it to my truck, now my Check engine light does not light up when I turn key to the On position, no crank at all! my friend is telling me that the ECM is bad!

Is there someone that can maybe give me a hint on this? Truck was running!
