the crank sensor is what tells the coil pack to fire. The coil pack is like an ignition coil and distributor all in one. Except instead of the rotor telling it to fire, an electronic signal does. But the crank sensor is behind the timing cover, which is a sealed system, and shouldnt be exposed to any moisture.
