It could be a bad coil but it could also be something else. If all of the wire connections to the coils are clean and snug, including the ground strap which is under the coil, try switching the spark plug wires around from the top to bottom coil and vice versa. If the bottom cylinder still has no spark, I’d suspect the coil or the plug lead. The terminals inside the ends of the plug wire, especially at the spark plug end, can become loose or corroded causing a weak or no spark situation.
