Car wont start wont even turn over the lights are on so its not the battery?

If it will not turn over you have an electrical problem. Start by removing the battery cables and cleaning the cables and battery posts. If that does not solve the problem, then put a charger on the battery and let it fully charge. Turn on your headlights and try to start the car. If it still will not turn over and the lights do not dim you probably have a bad starter or starter solenoid. But make sure your battery is good. If you can jump start it with another vehicle the battery is bad. It can also be a defective ignition switch.
