Did both engines stop or were you looking at the 2 gauges behind the pilots control column? So far all I have been able to find out about the fuel system is from an accident report It said the fuel system is a series of interlinked tanks which are filled from a single fill point on top of the right wing. Fuel level is indicated on a single gauge. That guage is in the panel in front of the throttle quadrant This model has 2 additional gauges below the main flight instruments which are probably for auxiliary tanks and fuel appears to be used from these tanks first It's possible these tanks hold an hours extra fuel over standard I have just done a flight with only half fuel loaded and both these gauges were on empty from the start with the main fuel guage indicating 80 gallons. After about 15 minutes it was still indicating more than 75 gallons

Yes you are right not all injected engines start mixture idle cut off. And I suspect that probably all injected engines will start with the mixture full rich anyway. There are 2 fuel cutoff switches/engine both of which have to be turned on if you have selected a cold dark start There is the really obvious fuel cutoff switch by the magneto switch There is another guarded fuel/hydraulic switch in the overhead panel above the magneto switch which also needs to be turned on. Thus switch requires you to click on the guard to open it then click left click on tne switch revealed under the guard. The guard will then close automatically The engines wont run with either switch turned off Another thing I found is the engines won't start if the starter switch is held on. I programmed a keyboard short cut for my starter. If I held the key down until it fired up as instinct had me doing it would not start If I just pressed and released the key it fires up straight away

In real life most fuel injected engines are primed with the mixture rich to flood the system, then mixture to idle cutoff and crank the engine till it fires then move the mixtures to full rich. FSX does not work this way unless the developers have worked a specific fix around it.
