Fuel door won't open?

It's definitely weird. Not sure what the design reason is... Maybe to ensure no refilling while it's running and they made it to check ignition is fully off instead of engine is off...
It's part of the design of the Evaporative Control System. The system is designed to control the release of fuel fumes into the atmosphere. A check engine lamp will illuminate when fumes are able to escape from the fuel cap; therefore the system does not want to throw a false alarm, which would be caused if the fuel cap was open whilst the engine is running. Nanny-stateness at it's finest !!
