Old gas in the tank--Truck won't start

As usual OK4450 is right on the money…HOw many X have I started a post with that comment? Oh well give props when props are due is my motto…

YES like OK said…how much fuel was in the truck to begin with, because if it had 1/4tank or more this amount of stale fuel would do nothing to you…now if you were seriously foolish and added this to an empty truck tank then you are asking for trouble…so which is it? Its rather important.
