Hello, my name is***** you for the question. Did the vehicle die while you were driving it or did it just refuse to start all of a sudden?

Customer: replied 1 year ago.
i started it and it seemed fine but then i got the traction control off advisory and my fuel gage quit working. so i cut it off and now it wont even try to start
Expert:  BOBBYSS replied 1 year ago.

Thank you. Most of the time this is because of the battery cables. These tend to fail and cause a loss of voltage or can have poor ground connections. That is the most common. The second most common is a failing ignition switch. The ignition switch commonly fails and causes certain circuits to not function.

i have checked the battery cables and the radio still works so its getting power from the battery. i thought about the ignition but my interior lights wont come on and the back windows will not roll down. could that be related?
Customer: replied 1 year ago.
none of the controls on the steering column work either, i forgot to mention that.
Expert:  BOBBYSS replied 1 year ago.

Yes, the ignition switch can cause this. One other thing that will cause this is the body control module. As for the cables, it does not take much power to run the radio. I would check to make sure that you have battery voltage at the fuse box and then tighten and clean the ground connections.
