Cavalier won't Start

My 1996 Chevrolet cavalier will not start. It sat for two months while I looked for a neutral safety switch. New switch is in and brand new battery, Car does turn over. It gets close but no luck. I put new gas in. Any thoughts? I really need to get this running before the snow flies. Thanks

Turn the ignition switch to the ON position so the dash lights come on for two seconds and then turn the ignition switch OFF. Repeat this a dozen times and then try starting the engine.
