I was trying to push a firetruck on a parking area (using afterburners) after mission and ran out of fuel. Then I was able to start APU after engines shut down. Engines did not start anymore though.
When shut down both engines with fire sw, the VEN (nozzle) did not close on right engine.
Brake accumulator should deplete when at least right engine is off, the parking brake handle is pulled emerg and braking with pedals few times.
Cheers...
