If you know what cylinder it is, pull the plug and check it for fouling or wetness. If it is wet, it is either not firing, or compression is too low to support combustion. Do a compression test on the affected cylinder. It could be a wire, distributor cap, plug, or injector. The plug will give kind of a readout of which way to proceed.
