Why isn't the engine firing here?

I have full fuel and two activated engines. Full throttle. No thrust. The stack display says there's no fuel, but the resource display says full fuel/ox.

I use this lander module a lot. It has landed on the Mun and Minmus... and once on Kerbin SpaceX style. It's been to (but didn't land) on Eve. I know this thing works.

Why is this not working, now.

You cancelled the flow of liquid fuel from the tank. Look at the readout for the Rockomax X200-16 Fuel Tank and click on the red strike out icon.

Oh. I didn't even see that. I had something weird in the VAB where I couldn't adjust fuel. I must have accidentally hit that trying to get the fuel adjustment to work. Thanks.
