    Check to see if it is getting spark. If there is no spark, your cause is either a bad ignition control module under the coils or a bad crankshaft position sensor.

    I did check to see if it was getting a spark and it is. You are talking about when you take one spark plug out and but it against metal and it sparks when you turn the key. If so, yes it is getting a spark.

    You did not include that detail in your original details or I would have answered differently. Try unplugging the electrical connector from the Mass Air Flow sensor and see if it starts. if it does, replace the MAF sensor.

    Sorry about not including that in my first message. My bad. Unplugged the MAF and still did not start. It was almost like it wanted to start.

    The upper intake manifold is known to crack and cause raw coolant to be introduced into several cylinders.

    1. Remove the throttle body assembly.

    2. Inspect for a ruptured intake manifold at the Exhaust Gas Recirculation (EGR) passage. The passage will be located at the 6 o'clock position when looking into the plenum. It will be a hole approximately 5/8" in diameter at the throttle body mounting surface.
    The upper intake manifold cracks and it dumps antifreeze into the engine, causing it not to start.
