1997 5.2 grand cherokee no start
no spark,,,no voltage to coil,,, codes stored were 12,45,21, and a possible [45., may be 44 or 46, was checked by daughter in law, and the 55. possible crank sensor or coil??? has 200,000 miles too.

Welcome to CF.
Since you stated the ASD relay and all fuses were good there's only a couple of things I can think of trying. Remove the distributor cap and verify the rotor is turning when the starter is turning over the engine. Wouldn't be the first time the dist. drive had sheared off. That would prevent the pick-up from sending a signal and the coil from creating a spark. IMO.
If that's okay check the pick-up in the distributor.
