  Q:

  How to service the fuel rail assembly on Dodge Ram 1500 Van?

  A:

  Before servicing the fuel rail assembly, always let any fuel system pressure out. Lift off the engine cover, remove the negative battery cable and get rid of the air cleaner. Preform the fuel pressure reset, then take out the throttle body from the air intake manifold. When air conditioning is installed, you must take out the A-shaped support bracket connected between the A/C compressor and intake manifold with these three bolts. Disconnect the wiring connectors at each fuel injector labeled with an ID. Loosen the electrical connector at the intake manifold air temperature sensor for the 3.9L V-6; do not remove the sensor. Take off the fuel tube at the side of the fuel rail and then pull out the remaining bolts that secure the fuel rail. Remove dirt from every fuel injector at the intake manifold and then rock and gently pull the left and right fuel rails until the fuel injectors clear the intake manifold. Get rid of the entire fuel rail and its attached injectors and also remove the clips that hold the injectors on the rail. Put a drop of engine oil onto each O-ring of a fuel injector and then install both the injector and the clip onto the fuel rail. Center the fuel rail/fuel injector assembly over the intake manifold openings so that you can carefully seat each injector in place, not damaging the O-ring. Push the fuel rails down with the injectors fully seated and afterward, screw the fuel rail mounting bolts in place. Restart your connection to the manifold air temperature sensor and extend the wires to all the fuel injectors. Should this apply, fit the A/C support bracket and the throttle body back to the intake manifold. Bring the disconnected fuel tube together at the side of the rail, replace the air cleaner, connect the battery cable, start the engine to ensure there are no leaks and finally, reattach the engine cover.
