Re: The EWR MD80.. The way I heard the story (take it with a grain of salt--you specify the exact size) is that the overnight MX folks had 2 tasks to accomplish. The first involved working on somthing close enough to the throttle quadrant area in the cockpit that the one/both thrust levers were moved out of their normal idle thrust position (where they were upon engine shutdown).
Another overnight task was to check on of the engines for a reported leak, so another MX dude (supposedly independently of the first guy, and after he was done with his work) went to start the engine(s). (Most MX folks are qualified for engine runs and taxiing, but I digress). During the engine start process when fuel flow was initiated to the engine, it then lit-off, and the engine then responded to the power called for based on the position of the thrust lever, whic, as you'll recall, were not in their normal idle thrust position.
Gotta hate the midnight shift....
