Answer
Jeep

Hi, Vickie; Did you re-use all of the sensors from the old engine? If not, could be a compatibility issue with the computer? Recheck all of the connections. Jeep crank sensors are a common problem. Did you use the original flywheel? That is where the crank sensor gets it signal.
Good luck.

Make sure battery cables connected...

....both at battery, starter, and fusible link to the firewall. Check to make sure the alternator has it's wires connected too.
