So far pulling none of these mods has made it work even on a fresh save.
Behavior specifics:
Fluid enters the building, fills the GUI for displaying the fill level in the building
Building does not produce power
Building does not show up in power tab as a generator
Building does not play animations
Building does not play sound
Short of giving you my save file this is the most info I can give you. I have also confirmed the following noob mistakes are not made: 1. It is connected to an isolated grid with a Creative Mod Active Power Void (It draws infinite power from grid) when I was testing 2. It had fluid when I was testing 3. I tested it with crude oil, heavy oil, light oil, and petrol. 4. This was on Nauvis.
