Darn odd for it to be able to ignite the oil, although I'm sure once started, it would burn strongly. I would have expected it to smoke quite strongly before being able to ignite it. I wonder if a wire burned up and dropped into the usual oily mess on the pump, and the sparking wire is what actually caused the ignition.
