Answer
If it is cranking over but not starting the most common problem would be the Crank position sensor. This could be verified by connecting a scanner to the car and checking for codes. The sensor is on the engine block on the radiator side of the engine. 1 bolt holds it in place. One bit of advice, when you remove the old sensor make sure the "O" ring seal comes out of the engine. If not the new sensor will be too far from the tone wheel in the engine and it still won't run.
Hope this helps,
Good Luck
