Welcome to 2CarPros.
Since you have no spark, my first suspect is a bad crankshaft position sensor. Take a look through these links:

_________________________
Now, before I suggest replacing the sensor, we really need to be sure it is bad because it is behind the timing belt cover on this vehicle. What I normally would do is check for an RPM signal when cranking the engine using a live data scanner. If there is no signal from the crankshaft position sensor or no RPM signal, the sensor is my first suspect.

If you find it to be bad, here are the directions specific to your vehicle for replacement. The attached pics correlate with the directions.
