I have a 2009 JKU with about 120,xxx miles. I hydro locked the motor a little over a year ago. I’ve replaced everything from the flywheel forward, including a brand new crate 3.8. When I turn the key to start it I’m hearing a slight thud coming from just on the other side of the firewall behind where the radio would sit. I backed the starter bolts out some but left the electrical portion plugged up, when I turn the key the starter doesn’t spin or make any noise at all. Any ideas?

 

Welcome to JKF BTW.
Ground cable missing??? Battery gone?? Get those bolts back in or you my damage ring gear teeth.

 

Brand new battery and ground cable. Any knowledge about a IOD fuse?
