Either the coil is no good or more than likely there is a poor electrical connection. Usually right at the plugin, may be a wire broke inside the insulation. Do a continuity test on each wire from the plugin back a ways from the plugin and move the wire around watching your readings on the digital multi-meter. It should stay at 0.000Ω.
