Is it trying to start. Is the battery good? Starter good? I'd look at the fuel filter. Could be clogged not allowing fuel to pass.

the selonoid is fine if it turns over...if it is not firing at all...probably the dizzy module. or possibly the inertia switch, you can bypass that for a minute just to test it.
