Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

So long as every wire in the harnesses have been checked and you are 100% sure they are not the problem and there are no poor/loose connections such as at a harness pin being pushed in, too far open, corrosion, etc, then I would lean towards the ecm if the problem is lack of communication and engine not running as a result. This one may help to know if the problem is simply loss of communication such as to the gauges or loss of communication with ecm and engine not running as a result, knowing the full extent of the symptoms.

Thank you!
- Joe
