Check to see if the fixture itself is grounded. It should be. I have found that grounds not connected to the fixture ground can cause erratic performance in fluorescent lights.

If a bulb demonstrates that it is capable of lighting, I'm curious what could be wrong with the bulb to prevent it from lighting at another time.
