                When the key switch is turned to "ON", the ECU
                activates the fuel pump, which pressurizes the system for
                start-up.
                The ECU switches off the pump preventing the continued
                delivery of fuel in these instances:
                • If the key switch is not promptly turned to the "start"
                  position.
                • If the engine fails to start.
                • If the engine is stopped with the key switch "on" (as in
                  the case of an accident).
