FUEL DELIVERY Automatic Shutdown (ASD) Relay ASD relay is energized when ignition is on. If PCM does not receive a distributor signal (camshaft or crankshaft sensor signal on DIS models), PCM will de-energize ASD relay. When ASD relay is de- energized, power to fuel pump, fuel injectors, ignition coil and O2 sensor heater element is interrupted.

This relay is in the under hood fuse block(power distribution center).
