I shut my car off and ten minutes later, it won't start. I've tried to jump it, I've changed the starter and the starter switch. Any other ideas as to what may be the problem?

Probably did not need a starter motor and "switch". Have you used a diagnostic tool to monitor component operation? I'd sure be interested in seeing what transmission gear is showing as selected. Perhaps it's not "Park" or "Neutral" and as a result will not crank. Checking all cabling and connections is helpful also. www.repairpal.com/repair-shops
