High Pressure Fuel Shutoff Solenoid Relay

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.

This relay is located in engine compartment and is comparable to fuel pump relay used on gasoline powered vehicles. Relay is controlled by PCM and is used to control the high-pressure fuel shutoff solenoid in the fuel pressure regulator. Relay also causes ASD relay to deactivate due to a common ground circuit.
