There are limited things to get spark to plugs. Battery to coil pack to plug wires to plugs. This may sound silly, but if you haven't had spark from the time you serviced the coil, I would see if you released the lock on the battery lead and plugged it in all the way and closed the lock. Simple battery voltage to coil. If that's not it, check that wire for continuity as it may have gotten tugged and the clamps are grounding it. Other than that I'm lost to.
