So, you have power to the coil (determined from the successful test of both the #1 and #15 terminals) but no spark. There are six possibilities, starting with the least likely.

1. Bad ignition computer. Very unlikely. Almost non existent rate of failure.

2. Bad coil. Your test showed that the primary winding is intact. Coils almost never go bad, and when they do, there are usually notable symptoms, like smoke or a burning odor.

3. Broken timing belt. You tell us that the cam is turning, Strike this one.

4. Bad #6 fuse. You mentioned that you replaced this. To be sure, ground your test light, key in the KP II position, and probe both sides of the #6 fuse holder. Should light both times. If not, try cleaning, replacing, etc.

5. Bad power stage (aka ignition amplifier.) You just replaced this one.

6. Bad or failing crankcase position sensor, or CPS. Most likely cause. Wet plugs should have eliminated this as a possibility, but I can imagine a scenario where an intermittent failure would let the fuel system initialize, but not provide a spark consistently, Unfortunately, no easy test for this one. I'm not a big fan of throwing parts at a problem, but you seem to have eliminated the other likely causes.

I didn't include jumped timing, because explaining how to determine would be difficult.

If it were me, I'd replace the CPS.
