Fuel Rail Shutoff Valve
WARNING: This page is about a different variant/trim than selected.
The fuel rail shutoff valve is a normally closed valve that opens when terminal No. 80 is grounded by PCM. See Fig 1. Resistance of the fuel rail shutoff valve coil is 11 ohms. When ignition switch is in ON position, power relay is turned on. Power relay provides power to PCM and control side of fuel shutoff valve relay. Relay provides voltage to fuel rail valve. If ignition switch is not in START position, PCM will close fuel rail shutoff valve after one second. PCM will open valve, along with the tank valve(s), to provide fuel while cranking. The valve will remain open when engine is running unless IFS switch is "tripped".
