I have a problem with Boeing 747-800i. Even though all fuel pumps are turned on, only engine number 4 is being active. All other engines are not being fed.
I think you need to turn off the right side fuel Xfeed. I noticed the right side is on, while the left side is off
Yes, thanks. The problem was that a key on my joystick that was assigned to the engine start, switched off the fuel valves. I fixed the problem and now it works properly.
