How to replace the Fuel Injection Fuel Rail Assembly for Bank 2 (LLT) (3.6L) on Buick Enclave?

Question

Accepted Answer

Before starting the fuel injection Fuel Rail assembly for bank 2 (LLT) (3.6L) replacement process it is necessary to drain the fuel system pressure using ch-48027 or without it. Start by removing the fuel pipe shield as well as high pressure fuel sensor and Fuel Rail crossover pipe before discarding the crossover pipe. You should remove the Fuel Rail bolts and lift the bank 2 Fuel Rail from the engine while easing its rear section for complete extraction. You must discard the direct Fuel Injector hold down clamps since rebuilding the direct fuel injectors becomes necessary when they are taken off from their Fuel Rail or cylinder head position. Recovery of the Fuel Rail requires you to rebuild all the fuel injectors. The rebuilt direct fuel injectors need installation on cylinder heads with new hold down clamps to secure them. Position the new Fuel Rail by placing the front over the front injector then rotating the rear segment downward while applying gm p/n 12345610 (Canadian P/N 9931930) or equivalent silicon-free engine oil to the Fuel Injector cups. Begin installing the outer Fuel Rail bolts first before moving to the inner bolts while keeping all valves by hand. The first step in tightening bank 1 Fuel Rail bolts should be with a torque of 12 nm (106 lb in) followed by reaching a final torque of 23 nm (17 lb ft). Place new crossover fuel pipes on the rail before installing the high pressure fuel sensor. First connect the electrical connector of the Fuel Injector wiring harness to both the fuel injectors and Fuel Rail as well as the Fuel Pressure Sensor. To detect fuel leaks you should enable the ignition for two seconds while the engine is off followed by a ten-second off period before ending with a vehicle off ignition state to conduct leak examination. Tier the installation by putting in the fuel pipe shield and low side fuel pressure service port cap and fuel tank cap.
