Narrative:
After pushback, while attempting to start #2 engine, after bringing the #2 fuel control lever to start, I noticed the ignition switch was still in the off position. I discontinued the #2 start and started #1 while #2 wound down to zero RPM. While reattempting to start #2, we experienced high egt and a significant 'torch.' it was then that I noticed that I never brought the #2 fuel control lever back to off, thus the #2 was never purged of fuel. The rampers signaled me with a flashlight of the problem and I closed the fuel control lever and immediately began to motor #2 to put the fire out. #2 egt got up to 480 degrees C. We shut #1 down and were towed back to the gate. The entire process took 10 mins from pushback to towing in. I can't think of any contributing factors other than the crew being tired.
