Car will not start

Hello my name is Dave.

I need a little help to understand your problem better, when you shut if off in reverse were you not able to get it to go back into park? If you have gotten it into park is the engine turning and not starting? If you haven't been able to get it into park you can always try putting into neutral as it should start when in neutral. If you could fill in the information so we know what direction to guide you that would be very helpful and thank you for using 2CarPros!
