Good afternoon,

I attached the location of the relay for you. The auto shutdown relay controls the operation of the fuel pump.

The Auto Shut Down (ASD) Relay controls power to the ignition coil, fuel injectors, and electric fuel pump. Controlled by the Engine Controller the ASD supplies power to the ignition coil, fuel injectors, and electric fuel pump at all times when the ignition switch is in the start position. When the ignition switch is in the run position and the engine control module is receiving reference signals from the distributor, power will also be supplied. If there is no reference signal after two seconds the engine control module will de-energize the ASD and no power will be supplied to the ignition coil, fuel injectors, or electric fuel pump.

I attached a wiring diagram and the location of the relay below for you.
