i'm getting no spark on a quad 4 ohc. there is no spark going to the igniton module. 1 wire in the plug has power but not of the others are doing nothing at all. what controls the spark to the module, where does it come from? also my scanner is saying "no communition" and the aldl plug has 3 wires and none of them have power with the key on or off, what could this be? thank you very much
