accidentally left key in on position, battery was dead and couldn't even get the key out. Tried to jump with cables and got the key out and the engine would turn over but not start. Reset security and only indicator light that stays on is for the engine.
My car wont start after leaving the key in the on position for about an hour. on 2006 Buick Rainier
You will need to charge the battery and test it. The battery is only three years old but could be failing. Fully charge the battery and have it tested. If you don't have a battery charger leave your car attached to a running car with your jumper cables. Ensure the battery connections are secure, clean and tight.
