Could be a couple of things, no power or grounds to BCM, control relay failure, BCM lost factory presets. What does a code reader say? You may have to go to a GM dealer and have the system reflashed. Has the battery been dead or removed prior to this happening?
No the battery hasnt been removed r dead. The code reader doesnt say anything but for cam r crank shaft sencor , o2 heater circuit, and distributor
It still sounds like the BCM has lost all of the factory presets, unfortunately only a GM dealer can put them back. Hopefully you don't have an intermittent connection problem between the BCM and power supply.
