2004 Chevrolet Trailblazer Q&A

2004 Chevrolet Trailblazer Question: I was driving my car and suddenly stopped.

I tried to turn it on and would not start. The gear shift turned loose and car would go on reverse when I pressed on the brake. -
Answer 1
Does it crank over when you try to start it? Do all the lights come on with key on? Need more info. -
