Went to de-winterize and no spark Indmar 340

[Wake4Summer]

Boat won’t start. 2005 Indmar 340 (catless).
Turns over fine, no spark.
I’ve hard wired the kill switch to eliminate that.

My 4 wires at the coil when key at ON position.
1: is getting 12v
2:10.8v
3: is saftey switxh
4: nothing

I just installed this coil at the end of last season, worked fine a few times before winterization.
Plugs, rotor, cap all new last season as well.
I’ve checked all grounds.
I’ve ordered another ignition coil, hoping my new one is just faulty.
Any other ideas?

All breakers in good standing?

I know you said you have a no spark condition, but do you hear the fuel pump priming? That would tell you if you have power back there.

What is the 10.8v terminal? Wonder why you're not getting closer to 12v?

Yah I hear the fuel pump whine and pressurize.
The 10.8 is also my concern. Really hoping it’s not the ECU. I’m hoping I can find my Clymer shop manual to check the wiring diagram.
