Fuel Pressure Regulator Control Solenoid (Capri)

  1. Locate PRESSURE CONTROL (PRC) solenoid on cowl panel, next to canister purge solenoid. Unplug PRC connector. Remove both vacuum lines. Plug one vacuum port. Apply vacuum to remaining port. Replace PRC solenoid if it does not hold vacuum.
  2. Connect 12-volt power to PRC terminals. If vacuum drops to zero, PRC solenoid is okay. Replace PRC solenoid if vacuum does not drop to zero.
