What would make a Grand Cherokee 2008 not turn over when trying to start

What is your question?

When turning the key in my 2008 Grand Cherokee it just turns but will not turn over what could cause the problem it has a automatic start that will not start if neither it just turns turns turns but will not turn over

What makes this problem better or worse?

Nothing at this point
