If it follows some of the logic of the newer euro trucks part of the out of fuel reset has the system ignore fuel rail pressure as part of the start up, the fuel pressure regulator is left in a more open position promoting fuel flow through the system. the engine runs at reduced power during this stage mapped back to whatever the limping fuel rail pressure is.
one of the nice things about modern common rail injection is that as your run out of fuel it runs out of power until the ecu shuts down on a low pressure error. So long as you dont have a leak elsewhere in the system its "almost" primed.
