Drove home okay. Turned off vehicle.
Next morning. Engine wont start. Turns over but wont start. Pulled spark plug lead. Turned over engine, no spark.

Possible cause?

Welcome to 2CarPros.

Any time spark is lost, my first suspect is the crankshaft position sensor. Now, testing it really isn't that hard, but it requires a live data scanner. Basically, plug in the scanner and check for an RPM signal. If none is found, the sensor is the most likely cause.

Here are a few links you may find helpful:
