Answer
    You need to find out if you've actually got spark.  Replacing the battery was a waste, if the engine cranks over the battery is doing its job.  Disconnect one of the spark plug wires, slide a screwdriver blade into the end that fits on the plug, and hold it very near (but not touching) one of the bolts that holds the cam cover or head on.  Have someone try to start the car.  You should see a bright blue spark between the screwdriver and the bolt.  If you don't see any spark, then either the ignition module or crank sensor is bad.
