Ok, I just went out and checked the resistance and voltages of the coil and the Ignition Control Unit. ICU seemed pretty good but the coil didn't. The resistance was low and the voltages were off. I know the obvious answer is "that's the problem" but I just want to be sure, I am not in a position to just start swapping parts in and out.
