1988 Other Chrysler Models No Start

Hey, dan here owner of a dodge 600. First question: is it dodge or Chrysler, or both? The main problem is no start. Checked fuel and spark both good. Has a ECM and feel its best to have a professional inspect, due to endless possibilities, but before I start there could you help with anything I could personally check. I do know that there is some minor leaks around the cylinder head indicating a bad gasket. Could it have finally failed filling the cylinder with something other then gas thus not allowing it to combust. Oh and also the cylinders appear to be dry when I pull the plugs, but I see fuel entering the intake. Any ideas would be a great help, thanks
