Are the wires routed properly to each cylinder? If two of the spark plug cables are going to the incorrect cylinders, you'll likely experience a no-start or heavy misfire situation. Double check the wires on the cap. The firing order, and that the wires are not only going to the proper cylinders, but that the wires are also intact. If you find excessive chaffing of the wires, they may need to be replaced. The insulation inside may have worn down allowing spark to arc to a nearby ground, such as the intake manifold or valve cover.
