This sounds like Skreem problem. I had the classic Skreem symptoms. 3 tries to start then nothing. Tried spare battery, no luck, then tried spare (RCM), no luck, tried spare CPS, no luck. Each time tried to start, nothing.

I changed out the Skreem myself. $200 Fix myself. Most of removing the Skreem are the sticky fix procedures removing lower panels. Gives access to screws to remove instrument panel screws. Did not remove steering wheel. Took out instrument cluster. Skreem right behind it. Unplugged it and removed it. Called SOS in California, they said they just replace them. No reprogramming them. Quoted $395 for Skreem. I called my local dealer, quoted me $200 for Skreem. Asked for my vin number, and car mileage. Ordered it, came back in 3 days. Package wrap said came from MB in Texas for Chrysler. I plugged it in. Put back the instrument panel and lower panels. Turned the key with battery disconnected to drain capacitors. Then connected battery, turned key to on position for several minutes, sounded like things were reprogramming themselves, then turned key off for one minute. Them started car as normal. Fired right up on first try. Drives great again. Total work time to do it, maybe an hour and 10 minutes. And the 3 day wait for the new Skreem to arrive. No core required for old Skreem, no fore charge. Just $200 part plus tax. Done deal. Hope this helps.
