  Q: How to remove the Fuel Rail and Fuel Injector(s) on Mitsubishi Galant?

  A:

  To remove the injectors and fuel rail, relieve the fuel system pressure and disconnect the cable from the negative battery terminal. For the 1994 and 1995 2.4L DOHC models, pull the spark plug wires out. From 1999 and later models, drain coolant system. Disassemble the top intake manifold for V6 Models. Remove the vacuum line and fuel return hose from the Fuel Pressure Regulator. You only need to remove the regulator from the fuel rail if you are replacing the fuel rail. Remove the screws, as on some vehicles you need to take the fuel supply off the fuel rail. To disconnect the electrical connectors from the fuel injectors, press down on the locking tab and pull off the connector. If your vehicle is a 1999 or later four-cylinder, discard the throttle body. Take off the fuel rail mounting bolts and.use compressed air or carburetor cleaner to clean around each injector. Take off injectors and fuel rail assembly as a single piece. Be careful to take off and store the spacers that sit between the fuel rail and the intake manifold. On V6 models, unclip the retaining clips and pull the injectors off the fuel rail, while on 2.4L models, pull the injectors off. Throw away the O-ring seals and put new ones on. To install the injector, coat the new O-rings with clean engine oil. Then, install the O-rings on the respective injectors. After that, Insert the injector into the fuel rail. Place the injector and fuel rail assembly on the intake manifold, ensuring that the injectors are firmly seated and the mounting bolts are tightened. Ensure the fuel supply line and return hose are securely connected. Next, attach the electrical connectors to each injector as per the number tag. Prior to the installation of the upper intake manifold, ensure the upper-to-lower manifold gasket surfaces are clean and checked on V6 motors. The rest of installation is this order reverse removal. Once the injector/fuel rail assembly has been installed, turn the ignition switch ON (not crank) two or three times, after which you would visually check fuel lines and injectors for leaks. If you have drained the cooling system, refill it.
