2009 Chevrolet Impala Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the Fuel Injection Fuel Rail Assembly on 2009 Chevrolet Impala?

  A: Before starting Fuel Rail assembly replacement writers should document the stamped 8-digit identification number located on the Fuel Rail because this information may be needed when servicing the rail. The correct installation of Fuel Injector o-rings guarantees safety by preventing fuel leaks; black rings should go above among rings that differ in color. The installation process requires you to cap the fittings along with plugging the holes to stop fuel system contamination by dirt. Disconnect the fuel feed pipe which connects the Fuel Rail to the system before removing all electrical connectors. First disconnect the Camshaft Position Sensor and engine cool temperature sensor electrical connectors from their positions before removing the upper Intake Manifold bolt and Fuel Injector harness bracket bolt at the Intake Manifold. First remove the Fuel Rail bolts then disconnect the Fuel Rail from its mounting points to access the spray tip end of each injector where you will take off the o-ring before discarding it. Before taking out the fuel injectors users must protect electrical connector pins or nozzles from damage while also refraining from placing injectors in any cleaning solution. The procedure includes taking off the retaining clip from the Fuel Rail next to removing the Fuel Injector followed by both the Fuel Rail and the upper o-ring. The correct part number of fuel injectors must be used for installation while cleaning engine oil should be applied to new injector o-rings followed by placement of the upper o-ring and injector on the Fuel Rail with secure retention using the required retaining clip. It is essential to protect the fuel system by plugging port openings between the Fuel Rail and preventing the use of compressed air or solvent baths for component cleaning. First replace any damaged lower o-rings for the injectors before lubricating them for installation into the Intake Manifold while slightly tilting the unit to add the injectors. Secure the Fuel Rail bolts at 10 nm (89 lb in), reconnect both cmp and ect sensor wires, put the Fuel Injector bracket into position on the Intake Manifold, then fasten this bracket with an 8 nm (71 lb in) torque. Place the upper Intake Manifold back into position while connecting available electrical connectors before joining the fuel feed pipe to the Fuel Rail. To complete the procedure conclude with Battery Cable reinstallation and perform a leak inspection while using a set ignition on/off sequence to verify there is no leakage.
