Narrative:

We completed the taxi checklist and were holding short of runway. As we approached the hold short marking we received a nac ovht warning. The captain called for the checklist. While obtaining the checklist for the nac ovht we received an engine 2 fire warning with a crc; #2 fire handle illumination; and fuel so illumination on the #2 condition lever. We immediately executed the memory items for engine fire on ground. I completed the QRH while the captain advised tower that we had an emergency and engine fire and would be evacuating the aircraft. No passengers were on board. The captain completed the ground evacuation checklist and advised the flight attendants. The entire crew exited the aircraft safely via the main cabin door.
