Crank sensor would not have anything to do with these electrical issues you mentioned. The crank sensor gives the engine computer the rotational location of the crankshaft. That is how the computer knows what piston is coming up on top dead center. It needs this info along with the cam sensor(in the distributor) for injector and spark timing.

Have you checked all fuses and all wiring for faults? Could be a hidden accessory left on draining the battery or faulty voltage regulator.
