Ok, I know this is late but my 2 cents. Chrysler has used a safety feature that will ojnly let the coil fire once IF it dosn't like what is sees in relationship to cam/ crank signels.
Now my story: A chrysler came in with a blown timing belt, and we were assighned to reassemble it. My friend did and gor the same results, As we had to use a mig on the car to get a broken stud out, we thought we could have fried the puter, but with a lot of testing and parts swapping we found this info on IATN. While this may not be the same engine, the theory can be the same.
Other commons to this engine: Flywheel cracked: Common in intrepeds Parts store cam sensors not up to par. Bad crank sensor-- seems to be common also
