Changed engine in my 1994 Intrepid ES with a 1995 3.5 engine. Left original wiring intact on the new engine. After re-assembly, the engine will crank, but the coils won't fire. If any one has any ideas, please let me know, otherwise I am about to put a bullet through my head.

 

Well, since no one figured this one out, it was a transmission sensor on the wiring harness that was torn off. I replaced the harness, plugged it to the tranny and it fired right up.

 

sorry i couldn't help, but at least it works right now.
