What are symptoms of faulty ignition coil?
Symptoms of a faulty ignition coil are power to the coil checked with a multi-meter and no power out checked by pulling any of the spark plugs, placing it back int the spark plug cap, grounding out the end of the spark plug against metal while you have someone turn the motor over lack of spark would indicate no power from coil. You can also check the output side of the coil with a multimeter but note that your reading will jump instead of staying constant.
