1992 yj with automatic transmission rebuilt and after we put trans back in now it wont start. Car always ran strong before rebuild now it seams to be not getting a spark? Changed the coil with a new one since it was the original and had a few cracks in it and still will not start. Any suggestions would be a huge help, scratching our heads on this one!

Check the crankshaft position sensor it may have gotten damaged or not connected.

if it was running good before then chances are that you either hooked something up wrong or damaged something.double check everything that you did

When we started the Jeep the first time the crank position sensor was not hooked up. When we found it and hooked it up no change. Is it possible I need to reset the CPU?

Well nothing bad will happen if you reset it, just disconnect the neutral for 5 mins.
