  Q: How to service and repair fuel injectors on Toyota Land Cruiser?

  A:

  Service and repair of fuel injectors starts with removing the V-bank cover and intake air connector followed by the fuel pressure pulsation damper while setting a shop rag underneath the delivery pipe before loosening the pulsation damper at a slow pace. Disconnection of the engine wire protector demands removal of the PCV hose from the PCV Valve followed by VSV for EVAP VSV and No.1 to No.4 V-bank cover bracket bolts along with engine wire protector securing bolts. The two wire clamps securing the engine wire need to be removed in order to disconnect it from the RH delivery pipe. The technician proceeds with the delivery pipe and injector removal by successively unfastening the return pipe bolt and dismantling the front fuel pipe with gaskets and union bolts before disintegrating eight injector connectors and detaching delivery pipes from the lower Intake Manifold to retrieve the delivery pipes and injectors along with spacers and insulators and extracting the O-ring and grommet from each injector assembly. New grommets require installation on every injector followed by gasoline application to new O-rings before placing them on injectors while pushing these assemblies into their delivery pipes through clockwise rotation. The injector connectors face outward and the spacers and insulators must be placed on the intake manifold before setting the delivery pipes and injector assemblies in position onto the lower intake manifold while using nuts for temporary security. The front fuel pipe installation requires new gaskets while its bolt gets torqued to 7.5 N.m. Secure the clamp on the fuel return pipe against the LH delivery pipe at 7.5 N.m before checking that injector movement is smooth. Replace O-rings if injectors show any wrong movement. Secure the delivery pipe nuts to 21 N.m torque while connecting the injector connectors. Creating a connection between the LH delivery pipe and engine wire requires wire clamps which will be installed to the No.1 engine hanger with engine wire protector securing through bolts. The installation includes reconnecting the PCV hose and VSV EVAP followed by reinstallation of the V-bank cover brackets. During the last installation steps place the fuel pressure pulsation damper and intake air connector while securing the V-bank cover by following guidelines that include spindle oil or gasoline lubrication of O-rings and proper reuse of O-rings.

  Q: How to remove the fuel injector on Toyota Land Cruiser?

  A:

  The fuel injector replacement requires discharging the fuel pressure from the system before starting work. The next procedure requires the removal of the power cable from the negative battery terminal. Following removal of the V-bank cover sub-assembly the air cleaner hose assembly needs to be detached. The next steps require the removal of the No. 1 engine cover sub-assembly along with the removal of the No. 3 engine cover. Proceed with separating the No. 2 fuel tube from the Fuel Pressure Regulator before removing the No. 1 fuel tube from the fuel delivery pipe on both RH and LH sides. End the fuel hose connection to the fuel delivery pipe located on the LH side. Unplug the ventilation hose and No. 6 wire harness connector from the fuel delivery pipe sub-assembly RH before uninstalling both secure bolts and pulling the pipe upward straight while maintaining both endpoints. Detach the device which keeps the delivery pipes apart and the four insulators from the cylinder head RH side. Follow the same steps to detach the fuel delivery pipe sub-assembly LH starting with connector No. 7 removal then unbolting 2 fasteners before continuing with the extraction procedure. To complete the removal process remove the fuel injector assembly by detaching the fuel delivery pipe and unconnecting the injector connector and affix a label to the injector shaft for easy reassembly. Proceed by extracting both the fuel injector O-ring along with detaching three clamps which will allow removal of the delivery pipe No. 6 wire harness on the right-hand side followed by another round of clamp detachment to eliminate the delivery pipe No. 7 wire harness on the left-hand side.
