Dustinhughes, yes, actually sensors can go wonky and periodically work and not work. This is usually leading up to a complete failure of the part. They are usually nothing more than a hall effect transistor triggered by a magnet on the rotating part. Every time the magnet passes the transistor sensor, it's supposed to close the circuit. But the silicon-silicon junction of the transistor can be getting ready to fail completely. Using an ANALOG resistance meter, or a NOID light, hook up to the leads from the cam sensor and crank the engine when it won't start. Watch the needle or NOID closely. Then do the same on the crank sensor.
Let me know what you see or don't see.
