Car not starting

[tta422]

Started car up just fine, backed it out to clean her up for a car show, After about an hour later I tried to start her up again and nothing. I have disconnected the battery in an attempt to reset the the computer. Still nothing. Any thoughts. All plugs have been checked. Battery has 11.91 volts.
