  Q: How is the Fuel Rail Installed on a 4.7L Engine on Chrysler Aspen?

  A:

  Before installing the fuel rail for the 4.7L engine, be sure that the Fuel Injectors are ready. Clear any dirt inside the fuel injector holes in the Intake Manifold and put a tiny bit of engine oil on the circular seal around each fuel injector to ease installation. Lay the fuel rail and injectors together so the injectors fit into the openings in the cylinder head, not damaging the O-rings in the process. Press down on the right side of the fuel rail till the injectors sit on the cylinder head shoulder and repeat with the left side. Put in and fasten the 4 fuel rail mounting bolts and then attach the 8 Ignition Coils. Attach the electrical connectors to the Throttle Body and fuel injectors, making sure they are held in place when tugged on gently. Attach the vacuum lines to the throttle body, add the 2 bolts for the air resonator mounting bracket to the front of the throttle body and secure the fuel line latch clip and fuel line onto the fuel rail. After that, secure the air box to the throttle body and then attach the Air Duct to the air box. Once you have done that, link the battery cable to the battery, start the engine and check whether there are any leaks.

  Q: How to Service and Repair a Fuel Rail on a 4.7L Engine on Chrysler Aspen?

  A:

  Before you begin any service or repair on the fuel rail, discharge any pressure in the fuel system, since it is always pressurized. Left and right fuel rails are replaced together and need to remain intact; do not separate the rail halves at their connector tubes which do not use clamps. Be careful not to bend or kink the tube lines while taking out the fuel rail assembly. To start, open the cap on the fuel tank filler tube before releasing the pressure in the fuel system. Disconnect the Air Duct and air box at the Throttle Body and then the negative battery cable. At the front of the throttle body, take off the air resonator mounting bracket and then unhook the fuel line latch clip and fuel line using a special tool. After that, take out the vacuum lines needed and press away the red slider on each of the eight injectors to separate their electrical connectors. A tag marking the position of each injector is found on the factory fuel injection wiring harness. Unplug all the electrical connectors at the throttle body sensors, after that remove the Ignition Coils and loosen the four bolts holding the fuel rail. Softly rock and tug on the fuel rail from the left side until the injectors start to clear the holes in the cylinder head and then do the same for the right side. When you're done, take off the fuel rail, along with the injectors, from the engine. If Fuel Injectors have to come out, use the proper procedure for removing them.
