Is your check engine light on? If the cranking sensor wasn't sending a signal to the computer, there should be a code stored.
Sometimes an intermittent fault won't set a code, sometimes it will.
With any no start, the first thing to check is the computer (scan). Then check for spark, fuel, compression and all related sensors, in that order.
If you encounter a problem with the ignition system, then you trace it from the plugs back to the coils. If the coils aren't being told to fire, then your issue is with the wiring harness/connectors, sensors or computer.
If you have a fuel problem, then you trace it from the pump forward to the injectors.
If you have both fuel and spark, then check the compression of the motor, as your valve timing may be off.
