• Q: How to Service and Repair a Fuel Injector on 2002 Toyota Tacoma?

  A: Service and repair of the fuel injectors begins with removing the air cleaner hose followed by the intake air connector assembly and the fuel pressure regulator before disconnecting the fuel inlet pipe while collecting leaking fuel into a container. The procedure starts with the removal of fuel pipes followed by connector disconnection and safe extraction of delivery pipes alongside six injectors. The operators must prevent droppage of components while maintaining injector load-free operation throughout the removal phase. Start by unfastening the delivery pipes together with six injectors by removing their four bolts. Next pull out the four spacers from the intake manifold and proceed to remove six injectors from their delivery pipes along with removing two O-rings and insulators from each injector. Begin the installation process by fitting new insulators to each injector followed by applying a gentle layer of spindle oil or gasoline to two new O-rings before inserting them onto each injector. Begin by installing the six injectors through the delivery pipes using counterclockwise and clockwise motion while facing the injector connectors outward. After placing four spacers on the intake manifold and positioning delivery pipes with six injectors correctly joined to the intake manifold and temporarily fastening delivery pipes to intake manifold bolts check the smooth injector movement before choosing new O-rings. The procedure involves connecting all injector connectors before installing the fuel pipe with four new gaskets and two union bolts which require a torque of 34.3 N.m then a final tightening of delivery pipe bolts to 13 N.m. Connect the fuel inlet pipe through temporary installation with two new gaskets and a union bolt along with a bolt while tightening the clamp bolt to 8 N.m (80 kgf.cm, 71 in.lbf) and the union bolt to 34.3 N.m (350 kgf.cm, 25 ft.lbf). Check the fuel pressure regulator followed by inspecting air assist lines and connections for loose fittings and sharp bends and damage after installing intake air connector assembly and air cleaner hose and as the last step verify for fuel leaks.
