I have an 03 ram 1500 with a 4.7l that cratered. I swapped in a 4.7 from an 04 Dakota. I am now getting no spark at all and it keeps tripping the crankshaft position sensor. are there any issues with the bcm and computers I need to address?

Sounds like the engine you used has a different crank wheel tooth count
