So I知 doing a motor swap on an 03 Dodge Ram 1500 with a 4.7 magnum. The new motor is out of a 07 dodge Dakota. I use the everything off my motor but the heads, and flex plate. The motor turns over but will not start. I知 thinking that the reluctor rings may be different on the motors. If so will this cause the crankshaft position sensor to malfunction causing the truck to not start. If this is the case can a swap the reluctor rings to make the truck start

 

Have to remove the crank to change the tone ring.
