Did you visually check for spark at the spark plug in question? You can use a digital multimeter, one lead touches the spark plug wire, don't take the wire loose or penetrate the insulation, the other leads goes to ground, metal part of engine. Engine running, This is an inductive reading, may show around 1/2 volt, compare to other plug wires. This test isn't conclusive, but, is non-invasive. An example, if the reading on 5 plug wires is around 1/2 volt and the other shows zero volt, I know where to start.
