Take the spark plug out, push back into it's pocket, set the spark plug on a grounded piece of metal, have someone crank the engine while the spark plug is grounded (but don't hold onto the spark plug, common sense right?) if a spark appears between the little arm the spark plug works, if it doesn't spark, replace with a new plug, and if the new plug doesn't start you have a faulty wire.
