2012 ram 5.7 4x4 sl turns over but won't fire off and crank
 

Hit a bump and the truck stalled and died. Won't start all the way back up just continues to turn over but won't ever crank all the way up and run.

Something got knocked loose. Start checking connectors at the various sensors.

I've got it at the mechanic right now. It is not getting fire to the block is what he told me and not creating and rpm

Crank sensor.
