Fuel System Pressure Test

  1. Release fuel system pressure. Remove cover from service valve on fuel rail. Connect Fuel Pressure Gauge (C-3292) and Adapter Hose (C-44749) to service valve. Turn ignition on. Depress Actuator Test Mode (ATM) button on Diagnostic Readout Box (C-4805) to activate fuel pump.
  2. Check reading on testers after system is pressurized. Correct pressure reading should be 53-57 psi (3.7-3.9 kg/cm2 ). If system pressure is correct, remove testers. Replace cover on service valve.
