Checking Residual Pressure (9-5 - 2.3L)

Remove the valve cap. Connect the Pressure Gauge Equipment (83 93 852) and the Fuel Pressure Gauge Adapter (83 94 744) to the fuel-injection rail with the "safety" on. Take off the "safety" from the adapter. See Fig 1 .
Run the pump with the diagnostic tool until the pressure gauge stops rising. Stop the pump. The residual pressure after 20 minutes must be a minimum of 33 psi (2.3 bar). See Fig 2 .
Take a reading on the pressure gauge equipment.
Put the "safety" on the adapter and remove the pressure gauge equipment from the service nipple. Screw on the valve cap.
