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

  A:

  The installation process of the fuel injector assembly starts with applying gasoline to new O-rings which should then be placed onto each fuel injector. Cot both the fuel delivery pipe surfaces with gasoline before placing the fuel injector O-ring. You should install the fuel injector onto the fuel delivery pipe while avoiding O-ring twisting but after ensuring smooth injector movement. Replace the O-ring if needed. 4 new injector vibration insulators should be installed onto the cylinder head while installing 2 No. 1 delivery pipe spacers correctly on the cylinder head. Install the fuel delivery pipe with its attached 4 fuel injectors by securing 3 bolts loosely first before tightening everything to 21 Nm (214 kgf-cm, 16 ft-lbf). Make sure the fuel injectors stay securely in position without dropping and continue rotating smoothly. Insert the fuel tube connector into the fuel pipe until you hear a click and check the entire area for foreign matter and scratches before establishing the connection and test it by pulling the tube. After fixing the vacuum hose you should connect the No. 1 fuel vapor feed hose along with the fuel pipe clamp. Fasten the harness brackets with their corresponding bolts and tighten them to 13 Nm (130 kgf-cm, 9 ft-lbf). Also secure the 5 wire harness clamps. 3 bolts secure the engine wire harness with a harness clamp while the 4 fuel injector connectors need to be connected. The conclusion of the process involves installing the No. 2 ventilation hose while checking for fuel leaks before placing the No. 2 cylinder head cover into position.

  Q: How to remove the fuel injector on Scion xD?

  A:

  The first step to remove the fuel injector for the 2ZR-FE engine requires fuel system pressure discharge. The maintenance procedure starts with head cover removal from the No. 2 cylinder then moves to ventilation hose extraction. The engine wire harness needs disconnection by removing its 3 bolts together with the harness clamp and 4 fuel injector connectors. First disconnect all five wire harness clamps and after that remove two bolts to detach the two harness bracket assemblies. The first step is to detach both the No. 1 fuel vapor feed hose and the vacuum hose before unfastening the fuel pipe clamp. Before disconnecting the fuel tube sub-assembly pinch the retainer of the fuel tube connector then pull it out using your hands while taking care to prevent foreign material from reaching the connector and to avoid using tools or forcing the nylon tube. Replace the harness parts with vinyl bags after unlinking them. The process of releasing stuck fuel tube connector and pipe requires both pushing and pulling actions. To extract the fuel delivery pipe sub-assembly you need to unattach the bolt together with the 2 additional bolts but be careful not to let the fuel injectors fall. The technicians need to pull 4 fuel injectors out of the fuel delivery pipe after they remove both No. 1 delivery pipe spacers and all 4 injector vibration insulators. The technicians should keep the injectors in plastic bags to prevent contamination.
