Hymnals galloper won't start

Sounds like you may have tripped the anti-theft system. Do you have a Key Fob (the remote lock/unlocker) for the vehicle? If you do, use that to unlock it and give it a shot. Otherwise, unlock the driver's door with your original key, not one cut at Ace or something if you can avoid that and try to start it. If still a no-start, put the key to the "On" position and look at the lights on the dash and around it. Look for anything that says "Security" or something similar, it's usually a red light. If it's lit solid or flashing, I'd say you tripped the system.
