There are three ignition coils. To test their outputs, disconnect one plug wire with some kind of a specific distance to ground and crank the motor over. There should be a strong and consistent spark output to ground. If there is nothing or a weak spark, re-connect that plug wire and check the output from the other plug wire connected to the same coil. If it is still weak or nothing, check the resistance of the plug wires, should be between 12-15 Kohms or so. If the wires are good, check the resistance across the coil's output terminals, should be very low, 1-2 ohms. If that is all okay, remove the coil by removing the two bolts and check for power and grounding to it from the modules connectors. If that is all okay, replace the coil. Good luck.
