Question: My 3rd cylinder is misfiring. What might be the problem?

I've replaced the fuel injectors & spark plugs. When I take the plug off the cylinder in question it runs the same as if it weren't getting power. There's spark but not sure if enough fuel is getting to the cylinder. Is there maybe a fuse that controls it or could this be a computer issue?

Otherwise, you might want to check compression and leak down in that cylinder.
