I am in need of some serious help here, so here it is...

Changed engine in 1994 Intrepid. Everything works. When the car heats up, the engine will die whether you are driving or idling. When checked for a spark, coil is not operational. After vehicle sits for about an hour or two, it will again run fine until the engine is hot. I already changed the coil pack, but the problem persists. It's not the fuel pump either, due to the fact that there is simply no spark.

If anyone can offer some insight into this weirdness, I would greatly appreciate it.

Thanks.

 

this is not something that is easy to diag without actually having vechile in front of me but when it dies out does the check engine light come on and does it start to sputter then die or just die.

 

cam sensor or crank sensor
