  Q: How to service and repair the fuel injector on Scion xB?

  A: The procedure for servicing and fixing fuel injectors begins by removing the circuit opening relay (Marked C/OPN) from the instrument panel junction block to discharge fuel pressure. The engineer starts then stops the engine which leads to switching off the ignition and verifying engine non-start-up. The vehicle requires emptying fuel tank air through the cap removal and negative battery disconnection for a minimum 90-second period to stop Air Bag and seat belt pretensioners from activating. After removing the 4 nuts and No. 2 cylinder head cover, proceed to take out both the ignition coil and cylinder head cover sub-assembly. Disconnect the fuel tube sub-assembly through a combination of Special Service Tool: 09268-21010 along with removing the fuel pipe clamp while cleaning the connector beforehand and wrapping the separated pipe and connector with a plastic bag for protection. The process requires separating the fuel delivery pipe from its sub-assembly through disconnecting 4 fuel injector connectors and removing 3 bolts then carefully extracting the fuel pipe with the 4 fuel injectors while removing the 2 spacers from the cylinder head. You must detach the fuel injectors from their delivery position before removing the 4 O-rings and 4 insulators together with 4 fuel injectors. The installation method requires new insulators for each fuel injector and then you must apply a thin layer of grease or gasoline to the O-rings before positioning them correctly without rotating the parts. The fuel delivery pipe installation requires torquing bolt A to 19 N.m (194 kgf.cm, 14 ft.lbf) while torquing bolt B to 9.0 N.m (92 kgf.cm, 80 in.lbf). During this process, check for smooth rotation of the injectors. Attach the 4 fuel injector connectors before connecting the fuel tube while inspecting for damage and foreign objects and properly aligning the connector to the pipe. Secure the connection well. Place the fuel pipe clamp then attach the cylinder head cover sub-assembly together with the ignition coil. Reconnect the negative battery terminal after you check for fuel leaks and proceed to install the No. 2 cylinder head cover by first tightening nuts marked A to 7.0 N.m (71 kgf.cm, 62 in.lbf) then move to tighten nuts marked B to the same torque.

  Q: How to service and repair the fuel injector on Scion xA?

  A: Service and repair operations of the fuel injector begin by executing the following procedure: first remove the circuit opening relay (marked C/OPN) from the instrument panel junction block and start the engine until it stops and then turn the ignition switch OFF to check for engine start. The system must breathe through an open fuel tank cap alongside battery terminal disconnection for 90 seconds to block the Air Bag and seat belt pretensioner activation. Start by eliminating the 4 nuts and the No. 2 cylinder head cover from the sequence followed by removal of the ignition coil and the cylinder head cover sub-assembly. To disconnect the fuel tube sub-assembly use Special Service Tool: 09268-21010 while cleaning the connector first and applying a plastic bag for covering the disconnected pipe and connector. The fuel delivery pipe assembly removal starts with deconnecting 4 fuel injector connectors then three bolt removal and precise withdrawal of the combined fuel delivery pipe with 4 fuel injectors before extracting 2 spacers from the cylinder head. Pay attention to the 4 fuel injectors situated on the delivery pipe when replacing O-rings and insulators. Installation requires new insulators on each fuel injector with light grease or gasoline application to new O-rings then fuel injector insertion into the delivery pipe without rotating O-ring position. Install the 2 spacers on the cylinder head followed by the fuel delivery pipe with the 4 fuel injectors and torque bolt A to 19 N.m (194 kgf.cm, 14 ft.lbf) and bolt B to 9.0 N.m (194 kgf.cm, 14 ft.lbf) until finished connect the 4 fuel injector connectors. Check for any damage on the fuel tube and clear foreign objects before connecting its components with proper alignment of the tube to the pipe until a connecting "click" sound occurs. After installation of the fuel pipe clamp place the cylinder head cover sub-assembly along with the ignition coil before reconnecting the negative battery terminal. Install the No. 2 cylinder head cover by tightening nuts marked A first then nuts marked B to 7.0 N.m (71 kgf.cm and 62 in.lbf). The system needs initialization steps after you reconnect the battery terminal which has a negative (-) charge.

  Q: How to install the fuel injector assembly on Scion tC?

  A: Engine installation of the fuel injector assembly for the 2AZ-FE starts with a gasoline or spindle oil coating of new O-rings which needs to be installed onto each fuel injector. Before installing fuel injectors onto the fuel delivery pipe you should apply gasoline or spindle oil once to the O-ring on the pipe then repeat the application before installation. Before installation verify that the O-ring remains intact without its being jammed. Inspect the fuel injectors to ensure their smooth rotation throughout the process. Replace the O-ring in case of failed smooth rotation. The fuel delivery pipe sub-assembly requires installation of 4 new insulators into the cylinder head before adding the 2 delivery pipe spacers. The 4 fuel injectors must be installed onto the fuel delivery pipe before temporarily tightening the 2 bolts while maintaining constant vigilance to avoid dropping the injectors. Inspect the fuel injectors for effortless rotation before tightening their mounting bolts to 20 Nm (205 kgf-cm, 15 ft-lbf). Before closing the assembly connect the four fuel injector connectors while installing both wire harness clamps. Fasten the No. 2 ventilation hose to its ventilation valve position while aligning the paint mark which matches the hose clamp direction. Fitting the fuel tube connector requires a click then you can place the fuel pipe clamp while securing the fuel tube in the fuel hose clamp. Reattach the cable to the negative terminal of the battery while installing the air cleaner cap sub-assembly and the engine cover sub-assembly. Perform inspections for fuel leakage and execute system initializations with attention to systems that need initialization when disconnecting and reconnecting the negative battery terminal.
