• Q: How to Service and Repair a Fuel Injector on 2001 Toyota Tacoma?

  A: The process of servicing fuel injectors begins with removing the air cleaner hose and intake air connector assembly together with the fuel pressure regulator while disconnecting the fuel inlet pipe into a liquid container for handling fuel leaks. Remove the fuel pipe while disconnecting injector connectors as you proceed to take out delivery pipes and injectors without dropping them and maintain secure soldering of the injectors. After removing 4 bolts and delivery pipes with their 6 injectors you can extract the 4 spacers from the intake manifold and then draw out 6 injectors from delivery pipes while discarding 2 O-rings and insulators from each injector. Installation requires you to add new insulators to each injector followed by application of a light spindle oil or gasoline coating to 2 new O-rings before inserting the O-rings onto the injectors. After turning the injector with strict clockwise and counterclockwise movements place it into the delivery pipes until the injector connector faces outward. Temporarily install the 4 manifold spacers on the intake manifold surface then place delivery pipes with their 6 mounted injectors in position. The installation requires 4 bolt fasteners to maintain delivery pipe position at this stage. Verify the injectors rotate easily during this step; replacement of O-rings may be needed when rotation is limited. Secure the injector connectors before installing the fuel pipe using 4 new gaskets and tightening two union bolts to 34.3 N.m (350 kgf.cm, 25 ft.lbf). Next, tighten the four delivery pipe installing bolts to 13 N.m (130 kgf.cm, 10 ft.lbf). Secure the inlet fuel pipe to its position using 2 newly installed gaskets, a union bolt, and a bolt followed by bolting down 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). Follow these steps to install the fuel pressure regulator before examining the air assist lines for loose connections and inspecting bends for damage or sharpness. Then attach the intake air connector assembly to the fuel appliance and check for fuel leaks.
