Check the positive side of the coil is has a 12 volt while the key is turn to the on position. Confirm this preferably with a multimeter instead of a test light. If 12 volt is present bench test the coil. Connect a spark plug to it using one of the wires, and connect the metal body of the spark plug to the negative side of the coil. Using a 12volt battery, connect the negative side to the negative side of the coil. Momentarilly apply 12 volts to the positive side. Voltage should be applied very quickly, and and disconnect right away, do not leave the battery connected for longer than a fraction of a second or you will burn up the coil!! Voltage should only be applied momentarilly as if you were trying to create a spark. The high voltage should be induced and cause the spark plugs to fire. Avoid touching any metalic part of the circuit while testing or you will get a nasty shock!! If the coil fires then the most likely cause of the problem is the module.
