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

  A:

  Refrain from service or repair procedures on the fuel rail until all safety protocols are implemented because fuel components possess high flammability. Remove the ground cable of the battery and drain fuel system pressure to stop accidental fuel spattering. The technician must disconnect fuel tubes before taking out both the Throttle Body (TB) and exhaust gas recirculation (EGR) system module linked to the exhaust manifold tube. The service starts by disconnecting the Drive Belt accessory and unfastening the generator cable then disconnecting the connector along with the pin-type retainer and removing the mounting bracket bolts. If you want to separate the fuel charging wiring pin-type retainer from the crash bracket you have to first disconnect the vacuum tubes and electrical connector then remove the bolt and stud. Disconnection of the ground connector from the RH rear stud and the generator harness retainer from the LH front stud should be followed by disconnecting the eight fuel injector electrical connectors. The technician should detach the crankcase ventilation tube then separately unplug the vacuum tubes with electrical connectors from the evaporative emission (EVAP) Canister Purge Valve. Additionally disconnect the fuel rail pressure sensor including the temperature sensor and the vapor tubes with electrical connectors from the evaporative emission (EVAP) canister purge valve. The fuel rail removal begins with the uninstallation of four retaining studs that allows the fuel rail assembly to be extracted with its fuel injectors. Dispose the O-ring seals at this time. To install the fuel rail assembly use new O-ring seals from fuel-resistant materials while applying clean engine oil to the injectors before installation into the rail. Connect the fuel rail with the injectors by using an assembly method while tightening each fuel rail stud to 10 Nm (89 lb-in). After reinstalling the crash bracket along with its associated bolt and stud you need to attach the vacuum tubes and electrical connector. Begin by reconnecting the EVAP canister purge valve electrical connector followed by linking the two vapor tubes before proceeding with the vacuum and electrical connector of the fuel rail pressure and temperature sensor. Reinstall the fuel charging pin-type retainer to the crash bracket after connecting the crankcase ventilation tube along with eight fuel injector electrical connectors. The generator mounting bracket receives its reinstall and bolts achieve 10 Nm (89 lb-in) torque during tightening. Generator cable and electrical connector and harness pin-type retainer receive their respective reconnections. The last step involves attaching the RH rear stud to the ground connector while installing the generator harness location retainer to the LH front stud and keeping the EGR system module-to-exhaust manifold tube as well as the TB and fuel tubes in place and reconnecting the battery ground cable.
