Fuel system
The fuel flows in the following order: fuel filter, low-pressure fuel pump, vapor separator, high-pres-
sure fuel pump, and injectors. The excess fuel at the injectors passes through the pressure regula-
tor and fuel cooler, and returns to the vapor separator.
When the engine start switch is turned on, the injectors of all cylinders operate before the pump
relay is actuated to prevent the injectors from sticking.
