All new still no spark

[Tauld1]

Here’s my problem. 1995 mercury 90 Hp Dynasty jet sport. No spark! I’ve tested and replaced just about every electrical component on my boat and still no spark. Here’s what I’ve tried so far. New stator, new flywheel, new crank sensor, new rev limiter, new regulator, new ignition switch, new switch box, tested the neutral switch (good) have 12 volts at new starter relay. New battery, cranks over good, new coils, aside from whole new wiring harness don’t know what to check at this point. Cleaned all connectors and grounds as well. Seems like no power to power pac and coils?!? Any help in what I might have missed would be greatly appreciated. Tony

Possibly the ECU?

Do you have a wiring schematic for it? That would go a long ways in figuring out what is supposed to have voltage, and what isn't, along with the ability to do some diagnosing for where voltage might be lacking.
