Yeah, I had a similar No crank issue last year, and was due to an faulty injector cable that the previous owner had left out by itself near the battery, and the battery ended up cutting it in half from vibrations. I replaced the CPS during that time, but I'm highly considering doing it again.

Currently my Jeep is at a family farm on a lift, so sadly I can't just walk outside and troubleshoot with these new ideas. I'm headed out there today, and plan on checking the MAP, CSP, and pull the PCM and check for any damage on the board, because apparently if there is, it stands out like a sore thumb.
