If you have power to the coil and its not going to the plug then the coil(s) are defective if it is coming out of the coil then I would look at the wires going to the plug...easy change out.. https://www.youtube.com/watch?v=jjFQyB6woZ8

Also, the coils need power to them, if joemom doesn't get you anywhere, need to track further back into the system.

Very possible the ignition module I agree, and or the pole piece, check to see if the two wires are still connected by pulling on them slightly
