Auto? Did you try moving the shifter around? Do a forum search for neutral safety switch. You need to supply more information if you want help. Did you check the battery and terminals? ....etc....

Check out my no start thread to see what I've been fighting:

Unplug your map sensor and clean the connector and plug it back in.

Your map sensor is located a the very back of the engine bay on the firewall, it will be a green connector.
