As mentioned already, if it isn't fuel, then next would be fire. (spark). If it was me, next I would take a spark plug and disconnect the coil wire, plug in a spark plug and have someone turn it over while watching for a spark. That should eliminate the wire to coil if it works. (hold the plug to the block with a pair of covered handled pliers/channel locks). If that worked, then I would do it with each plug wire off the distributor cap in the same fashion. On ours, the distributor cap was corroded. Replacing it this week before the holiday.
