was the impact from the collision on the pulley side of the motor?
the crank sensor code points to either the crank sensor or the wiring to the crank sensor i would have the harness for the crank sensor inspected it is on the bottom of the motor on the pulley side. due to that code i doubt its any of the other things you mentioned. when you get a trouble code like that its usually pretty accurate as to where the failure is

i have never seen a ignition switch cause this concern in my 25 plus years of automotive..it honestly sounds like a connector issue at the sensor or a chaff in the harness...which would cause your intermittent concern.. i have also seen hairline cracks in the sensor causing this...when a crank or cam sensor has failed it will cause loss of spark and or injector pulse... if it was a key or switch error or a pcm you would likley have a security code... sorry to sound like mister obvious.. just there is no point going on a wild goose chase when you have a cam or crank sensor issue
