I swapped my 2003 1500 5.7 with another 5.7 from a 2005 durango. I used all of the original sensors from the 03 and now the starter wont crank. The dash lights all come on. However, the gear selector has all the gears lit up. Also, I think my ground strap to the fire wall is snapped. But would that cause it not to turn over?

 

Check that the trans range sensor is plugged in, and the harness didn't get pinched somewhere during the engine swap.

 

HeyYou, you are a Rockstar. Thats exactly what happened. I plugged the harness back in and all is normal again. Thank you sooooo much.

 

Gotta love the easy ones.
