• Q: How to replace the Fuel Injection Fuel Rail Assembly for Bank 1 (LF1) on 2010 Cadillac CTS?

  A: The replacement process of the fuel injection Fuel Rail assembly for bank 1 (LF1) starts by profiting the fuel system pressure. Start by taking away the fuel pipe shield then proceed with removal of the Intake Manifold. Users should extract both the fuel feed intermediate pipe and the Cylinder Head from the system. The first step is to detach the electrical connector from the Fuel Pressure Sensor before removing both the foam insulation and cutting through the wire harness tie straps. The en-49248 (Injector Rail Assembly Remover) should be used to extract the Fuel Rail assembly with its integrated injectors by first removing the Fuel Rail bolts. The party should detach the Fuel Pressure Sensor while eliminating direct fuel injector hold down clamps and conduct injector rebuild if injectors were detached from the rail or Cylinder Head. After the Fuel Rail extraction it will be necessary to perform injector rebuilding operations. The installation process starts with placing the Fuel Rail with injectors even in the Cylinder Head followed by attaching new direct injector hold down clamps and hand torquing only the two outer Fuel Rail bolts to position the injector in its bores. First start and then hand tighten all other Fuel Rail bolts before using the specified sequence to apply torque to 12 nm (106 lb in) during the first adjustment and finishing with 23 nm (17 lb ft) on the final torque pass. Begin with reconnecting the fuel feed intermediate pipe and high-pressure fuel sensor and then proceed to link the fuel injector wiring harness electrical connector to the fuel injectors, Fuel Rail and Fuel Pressure Sensor. Turn the ignition on for 2 seconds before turning it off for 10 seconds and observing for any fuel components leaking from the system. You should empty lingering fuel from the injector well before placing the foam insulator onto the Fuel Rail. To conclude the process reinstall the Intake Manifold while also reinstalling the fuel pipe shield and Cylinder Head before capping both the low side fuel pressure service port and the Fuel Tank.
