GMC troubleshooting questions? Ask a mechanic for answers
Hello there, I am Cam.
I am Licensed technician at a GM dealership with more than 16 years experience.
Like you, I am a user of this website and as such, any billing questions should be sent to customer service.
I ask that you please provide details and communicate with me so we can make your experience here worth 5 stars! I am around most days but not every minute of every day. If you reply while I am offline, I will respond when I am next online.
I am reviewing your request and will post in a moment.Have you had this vehicle running at all or saw it running? On the surface it sounds like the keys are wrong, not programmed or you have a module that has failed, such at the theft module.What I suggest is this, do a reset.Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.If after the reset you still cannot get it going with a boost, then you will likely need a shop to see what codes are set and diagnose it from there.
