rt durango help please.

I've got a 99 non r/t. Had the tranny out for rebuild. These vehicles are very sensitive to grounds. The cam position sensor is in the distributor and the crank is pass side towards top of block. I don't have my wiring diagram handy but a lot of the sensors share common grounds. If I remember correctly there are mass grounds at the back of each head. Also there is a possibility they pinched a wire harness sliding the trans back into place. Or maybe if they disconnected any of the harness that a connector had a pin bent or pushed out. Just some quick thoughts on my end.
