WARNING:Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury. WARNING:This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow these instructions may result in personal injury. Release the fuel system pressure.
For additional information, refer to: Fuel System Pressure Release - 1.4L Duratec-16V (Sigma)/1.6L Duratec-16V Ti-VCT (Sigma)/1.8L Duratec-HE (MI4)/2.0L Duratec-HE (MI4) (310-00 Fuel System - General Information, General Procedures).

Connect the special tool to the fuel rail. | | | -
Connect the special tool to the fuel rail fuel supply line. | | | -
Connect the WDS pressure/vacuum transducer adapter to the special tools. | | | -
Connect the WDS pressure/vacuum transducer to the WDS pressure/vacuum transducer adapter. | | | -
WARNING:Allow the fuel to drain into a suitable container. NOTE:Make sure that the end of the bleed hose is higher than the bleed valve to prevent air flowing back into the fuel system. Turn the ignition switch to position II and open the valve on the bleed hose. Repeat the process until no air bubbles can be seen in the bleed hose. | | | -
Close the valve on the bleed hose. | | | -
With the fuel system pressure at zero calibrate the WDS pressure/vacuum transducer to display zero. | | | -
NOTE:The fuel system pressure should be 3.8 ± 0.2 bar after the ignition switch is turned to position II and it should maintain this pressure when the engine is running. Using the digital multimeter function in WDS, start the engine and measure the fuel system pressure. | | | -
Turn the ignition switch to position 0. | | | -
NOTE:The fuel system pressure should be 3.8 ± 0.2 bar after the ignition switch is turned to position 0 and should not fall below 2.0 bar after 5 to 10 minutes. If the fuel system pressure drops below this level a fuel pump module internal leak should be suspected. Using the digital multimeter function in WDS, turn the ignition switch to position II and measure the fuel system pressure. | | | -
Release the fuel system pressure.
