With the bad motor I was getting fire to plugs but now with new motor I am not getting fire to spark plugs. Why?
Motor went bad so I put in a motor from a 2004 Durango 4.7 now no fire to plugs. on 2004 Dodge Ram 1500
Something is not hooked up correctly, something might have gotten broken during transfer. Go back over everything again to see if something has been forgotten.
