  Q: How to replace the fuel injector assembly on Scion xA?

  A: The first step when replacing the fuel injector assembly consists of discharging fuel system pressure. Remove the cylinder head cover No.2 through the removal of its 4 retaining nuts. To begin remove the 4 Ignition Coil connectors and then remove the 4 bolts with the ignition coils. The ventilation hoses will need disconnecting before you remove the cylinder head cover sub-assembly through the removal of 9 bolts along with 2 nuts and 2 seal washers. The removal of fuel tube sub-assembly requires users to disconnect the fuel tube by detaching the fuel pipe clamp and utilizing Special Service Tool: 09268-21010 while also checking for dirt around the connector and refraining from bending the nylon tube. Detach the 4 fuel injector connectors before removing 3 bolts to carefully extract the fuel delivery pipe with its companion 4 fuel injectors without letting them fall. Install new insulators and O-rings onto the 4 fuel injectors before applying a small amount of grease or gasoline to each element. Connect the fuel delivery pipe sub-assembly with 2 spacers by ensuring the rotating motion of the injectors is smooth before attaching the 4 fuel injector connectors. The sub-assembly of the fuel tube receives installation after checking for damage and foreign objects while the fuel pipe clamp follows. Use seal packing (Part No. 08826-00080 or equivalent) on the cylinder head cover sub-assembly then install it with 9 bolts and 2 nuts and 2 seal washers and tighten all fasteners evenly to 10 N.m (102 kg.cm, 7 ft.lbf). Reinstall the ventilation hoses before you tighten the ignition coil No.1 with 9.0 N.m (92 kg.cm, 80 in.lbf). The last step involves checking for fuel leaks while installing cylinder head cover No.2 by first applying torque to nut A followed by nut B to 7.0 N.m (71 kg.cm, 62 in.lbf).
