What computer controls the starting circuit? pcm,ecu ecm?

does nothing. No clicking of the solonoid. Just like a totally dead battery. Chrysler replaced the ground straps but still sometimes won't make a sound when the key is turned. Other times it fires right up.

Chrysler just replaced 2 ground straps after I saw the answer to the problem online. 2 days later nothing for 2 twists of the key then started on the 3rd try.
