I am new to this forum so I'll keep it simple. Started my 2009 4dr Sahara yesterday and no problem. Tried to start a second time with only a single click. Today it started, no problem. Started it a second time and it sounded as though the starter was spinning; no crank. Tried again and starter kept spinning even with the key turned off. I suspect the starter is probably gone. Battery is reading at 12.56 with a Mar 2016 sticker date. Any suggestions or confirmations are welcome.
