I have a 2012 3.6L JK and I am having issues with starting. My jeep suddenly stopped working when I went to start it before work one day. The starter is engaging (I replaced it thinking it was the issue), but there is no crank from the engine. From what I saw the flywheel and ring gear look fine. I can manually turn the engine so the engine isn't seized and the battery is pushing out 12v which is normal. I am a "backyard mechanic" and this just has me stumped. Would appreciate all the help and suggestions I can get. Thank you in advance
