If you have no spark on all, or like 4 of the 6, cylinders your car will not run. If you have weak spark, which is more likely, will cause issues like rough idle, low power issues, hard to start.
Likewise if you have a fuel pressure issue you will not be getting enough fuel per cycle causing hard to start issues, misfire, no start at all (if bad enough).
If you have never changed the plugs I would recommend going ahead and doing that, I think its about $20 for 6 and lots of swearing if you still have all the OEM stuff in your engine bay. Since your car is old'er' you might at well change the vacuum lines also. I dont know how much you need for all the OEM stuff but it shouldn't be terribly expensive and it give peace of mind that you will not have a vacuum issue for a while.
Anyways, I am not sure how to test spark for a distributor, or how contacts on a distributor are supposed to look. I could make guesses but am no expert. I used one of these for my COP https://www.amazon.com/AMPRO-T71240-Energy-Ignition-Tester/dp/B00A8FO87S/ref=sr_1_8?s=automotive&ie=UTF8&qid=1474061791&sr=1-8&keywords=spark+tester and it worked but might not be needed for your situation. Testing wires, plugs, distributor and coil would be my first recommendations. Then check fuel pressure or vacuum leaks.
