FUEL DELIVERY
Fuel Pump
Output signal from ECM or PCM controls relay that operates fuel pump. When ignition is turned on, pump will operate for 2 seconds without ignition switch being turned to crank engine, after which time pump will be de-energized. In addition, if engine stops with ignition on, pump will be de-energized after 2 seconds. Pump operates continuously while ignition switch is set to crank engine, or when engine is running. Supercharged vehicles are equipped with a secondary fuel pump. Both fuel pumps operate under certain conditions.
Returnless Fuel System (S-Type)
The returnless fuel system is used to reduce fuel tank vapor. System does not use a return line or pressure regulator. Fuel pressure is controlled by PCM. A pressure relief valve, located at the front of the fuel rail, allows system to be depressurized before fuel system service.
