Crank angle Sensor

I doubt it's the crank sensor. Normally, the optical-style sensor on this car has one of two failure modes:

-- Intermittently shuts car off when driving. After sitting a period of time, the car starts and runs normally.

-- The car stalls never to start again until the crank sensor is replaced.

Since the crank sensor is critical not just for starting but also for the engine to run, it's not likely to have an intermittent issue that occurs only when attempting to start.

I'd suspect things like the coolant temperature sensor, which could monkey with mixture enough during start-up that the engine won't start. After the engine is actually running, the computer can typically adjust to any issues.
