Answer
Alex I am much beter with newer late model cars, but I'll give you some things that you can check. Remove any easily accessable spark plug and wire. With the plug connected to the wire hold the plug by the wire, and touch the plug end onto a good ground source (i.e. engine block or cylinder head). Have someone crank the engine over while you look for a good healthy spark from the plug. I suspect that you are missing spark. If you have good spark then you need to look at the fuel system. If you are missing spark then check for moisture in the ditributor cap or the plug wire boots. Use compressed air to remove moisture, wear eye protection. Leave the car in the sun to heat up and dry it out. I would ask this same question to some of the other guy on this site as they are more experienced with these cars.
