I assume the engine runs, if not possible timing belt problem........Have compression tested! Check for spark at that plug you pulled the wire from, possible wire, dist. cap or spark plug problem. Check for a vacuum leak and injector pulse or have this done. Do what you can cause you are right about the plug wire, it should "be different" when you put it back on the plug while eng. is running. Check engine light on?
