So, I'm not sure why, but the crafting injectors for fusion crafting are not accepting power. I've looked at other people having the same issue, but none of the solutions worked. I tried to make an Advanced Dislocator, which would explain the set up.

Here's what I'm using:

• I'm on StoneBlock 2
• 8 Wyvern Injectors
• 9 Wyvern I/O
• 1 Wyvern Energy Relay
• Tier 7 Core

From what people have said, it was due to the injectors not accepting power until you start the recipe. But the ability to start the recipe wouldn't even show up if I had everything in the right spaces.

It was also weird that I was able to make the injectors, and then the power stopped. I've tried restarting the game, and that didn't work either.

First, your crafting injectors are too far apart. You need to have a one block air gap between the core and the plane on which the injectors sit.

Second, ensure that the wireless crystals are set up correctly. You can still start the crafting process even if you have no RF present.
Though, of course, it will sit there and do nothing.

I've moved the injectors and even rebuilt the entire setup just to see if I might've messed up somewhere. The thing I'm confused about is that the injectors could accept power before, but now won't.

Even with the proper setup, this is the only thing I see...

Well, I'm not sure why the Dislocator doesn't work (even though JEI sys it should work), but everything work now. Hopefully this won't happen again...

Mind closing the issue, then?

That's an invalid recipe or the placement of the crafting injectors is wrong. You'd see the ingredients on the sides of the GUI and a big start button otherwise, regardless of power provided.
