• Q: How to service the fuel rail on 2000 Chevrolet Malibu?

  A: The service of Fuel Rail starts with using proper procedures to reduce fuel system pressure. The task begins through the collection of necessary tools which should include the fuel line wrench (J43013). Disconnect both the Fuel Rail feed tube from the Fuel Rail as well as the fuel return tube from the Fuel Pressure Regulator after removing the upper Intake Manifold. You should remove the o-rings of both fuel feed pipe and fuel return pipe before disconnecting the main injector harness electrical connector. Press the lock release on the Fuel Injector connectors then depress the tab and properly remove the connector from the injector. Match the tasks through two steps in this order: start by taking off the Fuel Rail injector electrical harness then unplug the Coolant Temperature Sensor electrical connector. The procedure requires the removal of Fuel Rail retaining bolts before taking out the Fuel Rail assembly by discarding the injector o-ring seals but saving the o-ring back ups for future use. Prevent contamination between Fuel Rail installments by plugging inlet ports and outlet ports of the Fuel Rail. Mount the Fuel Rail assembly inside the Intake Manifold while tipping it to place the injectors correctly before tightening the Fuel Rail attaching bolts to 10 n.m (7 lb ft). Complete the Coolant Temperature Sensor electrical connection then mount the injector electrical harness onto the Fuel Rail followed by fitting all injector electrical connectors while sliding the locks fully into their position. Before finishing the procedure install new o-rings on both the fuel feed pipe and fuel return pipe while tightening the Fuel Rail engine nut to 17 n.m (13 lb ft). You need to complete fuel return pipe installation at the Fuel Pressure Regulator before tightening both the engine fuel return pipe nut to 17 n.m (13 lb ft) and placing back the upper Intake Manifold. In the last step reconnect the negative Battery Cable then check for fuel leakage by following the specific ignition on-off procedure.
