2003 Ford Crown Victoria Fuel Rail Parts Q&A

• Q: How to service and repair the fuel rail on 2003 Ford Crown Victoria?

  A: Service and repair of the fuel rail requires first making safety precautions to keep away from smoking or open flames around gas components because flammable mixtures will be present. A technician should first disconnect the battery ground cable and relieve fuel pressure while disconnecting the fuel lines. The automotive professional must disconnect the throttle body and take off the EGR valve from its exhaust manifold tube when servicing gasoline-powered engines. Before proceeding with vehicles that contain natural gas engines perform the following steps: uninstall the drive belt and disconnect the fuel temperature and pressure sensor connectors. After detaching the generator cable and main fuel shut-off solenoid connector users need to disconnect the electrical connector and harness pin-type retainer before they remove the generator mounting bracket bolts. The return spring needs removing and both accelerator and speed control cables require disconnecting from their crash brackets. After disconnecting the pin-type retainer of the fuel charging wiring it is crucial to remove vacuum lines and electrical connectors from the vehicle system while recognizing absence of EGR vacuum connections in natural gas vehicles. First take away the bolt and stud to detach the crash bracket then disconnect each ground connector at the RH rear stud and the generator harness locator retainer from the LH front stud. Cutt off the eight connections which power the fuel injectors and also detach the crankcase ventilation line. The installation requires the disconnection of the vacuum line and electrical connector together with the evacuation of the vacuum line from the EVAP canister purge valve when working on gasoline engines. The four studs need removal followed by extraction of the fuel injection supply manifold along with fuel injectors assembled together. New fuel-resistant material should be used for O-rings while engine oil must be applied for proper fuel injector pocket lubrication. The fuel injection supply manifold and fuel injectors should be installed together before torquing the manifold studs to technical specifications followed by crash bracket installation using bolt and stud. The installation of gasoline engines requires attachment of the vacuum line to the EVAP canister purge valve and the vacuum line with electrical connector. After connecting the crankcase ventilation tube and the eight fuel injector electrical connectors and all vacuum lines with their electrical connector, remember natural gas engines will not need EGR vacuum connections. Connect the fuel charging pin-type retainer to the crash bracket after which install the accelerator and speed control actuator cables through the crash brackets before tightening the accelerator and speed control cables together with return springs and bolts. You should install the generator mounting bracket by tightening its bolts but for natural gas engines the installation process involves connecting the generator cable alongside the electrical connector and harness pin-type retainer followed by the main fuel shut-off solenoid connector, fuel pressure sensor connector and fuel temperature sensor connector. To complete the procedure first route the ground connector to the RH rear stud while using the generator harness location retainer at the LH front stud. Install the drive belt followed by reinstalling the EGR valve to exhaust manifold tube for gasoline engines. Then attach the throttle body before reconnecting the fuel lines and establishing a connection with the battery ground cable.
