Narrative:
We were at the gate and the boarding took an extra 30 minutes because they boarded too many passengers for the flight. We were within 500 pounds of minimum fuel for the flight as of the current flight release. The captain decided to taxi out single engine to conserve fuel. During the start of the number one engine we had a start valve open light illuminate in the cockpit. We pulled over and accessed the QRH (quick reference handbook). During this; another company pilot taxiing a different aircraft alerted us that smoke was coming out of the number one engine. Then the engine overheat light illuminated. We switched checklists to the engine overheat checklist and shut the engine down. The captain had ground call the fire trucks and had me call maintenance. He alerted the flight attendants and passengers. When the fire department arrived they visually inspected the engine and took temperature readings which were all normal. The captain asked the fire department to follow us back to the gate and I got a gate. The fire trucks followed us back and we deplaned through the jet bridge without further incident.
