I believe the answer to your question is that Short was pushed off and the car did not want to fire because it had a fuel line leaking. I pushed him half way around the track before it got enough fuel to catch at all. He immediately went to the work area to have it tightened while the rest of the field was being pushed off. It was tightened and he returned to the track before a wave lap or one to go was given for the start. Since the race had not started and he had not held up the start of the race I believe that is why there was no penalty otherwise I believe he would have had to go to the tail. Just my opinion.
