Hi,

If it won't start, chances are either it isn't getting spark to the plugs or fuel to the engine. Do me a favor. See if it starts for a couple of seconds using starting fluid. If it does, then we know it's fuel related. Also, here are two links. One explains how to check fuel pressure and the other ignition spark.

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
