Thanks for your time

Sounds like you might have a ground problem at the Constant Control Relay Module (CCRM). I'm not sure how to explain the lack of communication with the ECM though. Do you know that the scan tool used to work with this car? Have you checked the battery voltage when trying to start the car to make sure you got a good battery?
