Often times, a bad crankshaft position sensor will fail and the engine will lose spark. Take a look through this link:

Here are general directions for replacement:

Additionally, here is a link that discusses possible reasons why a vehicle will not start:

What you need to do is this, check to see if there is spark and fuel to the engine. One will most likely be missing or weak. Here are general directions for both:

If you find there is no spark, my first suspect would be the crankshaft position sensor. The Crankshaft Position Sensor is located at the lower right side of engine, near heated oxygen sensor #22. See the attached picture.

Let me know if this helps or if you have other questions.

Take care,
