Flooding Protection System

When the ignition is switched to "ON", but the engine is not cranking, the fuel pump will run for 2 seconds to raise the pressure in the fuel rail and shut off. After the engine has started cranking is the fuel pump turned on.

All fuel pump switching is controlled by the ECU. In case any of the injectors become faulty, this system prevents flooding by limiting fuel pump operation when the ignition is left on.
