• Q: How to replace the fuel injector on 2006 Toyota Matrix?

  A: The first step to replacing a fuel injector requires pressure discharge from the fuel system while you disconnect the battery negative terminal. Use a tool to remove the header cover number 2 after removing its two clips and two nuts. Connectors should detach the ventilation hose from the cylinder head cover. The process begins with fuel delivery pipe sub-assembly removal which requires disconnecting 4 fuel injector connectors then removing 3 wire harness clamps from clamp brackets and disconnecting fuel tube after taking off fuel pipe clamp No. 1. Pinch the connector retainer on the fuel tube before pulling it out to verify its cleanliness from outside materials and prevent part damage. Wrap the detached part with a protective vinyl bag. Push and pull actions should be used to release fuel tube connector and pipe when they become stuck. Start by removing 3 bolts from the fuel delivery pipe while keeping the fuel injectors secure until you successfully uninstall the pipe then eliminate the 2 delivery pipe spacers and 4 insulators from the cylinder head. The fuel injector assembly requires insertion of the 4 fuel injectors into the fuel delivery pipe after applying a light oil or gasoline coat to both the new O-ring and the delivery pipe contact surface. Next, check that the O-ring remains intact as well as ensure smooth injector rotation when installing the components. The installation process starts with delivering 4 new insulators inside the cylinder head and then adding the 2 delivery pipe No. 1 spacers with precise orientation. The 3 bolt installation of the fuel delivery pipe with installed fuel injectors can be temporarily tightened to check proper injector movement. To install the fuel tube properly align the connector to the pipe end and push until it clicks into position while checking for any signs of damage along the pipe. The torque specifications for bolt A are 19 N.M (194 kgf.cm, 14 ft.lbf) while bolt B requires 9.0 N.M (92 kgf.cm, 80 in.lbf). Check the fuel tube connector stability by pulling it and follow-up with the installation of fuel pipe clamp No. 1 as well as the 3 wire harness clamps before reconnecting the 4 fuel injector connectors. Screw the ventilation hose back to the cylinder head cover while orienting the hose clamp properly then attach the battery negative terminal with a torque setting at 5.4 N.m (55 kgf.cm, 48 in.lbf). Finish the installation by securing cylinder head cover No. 2 with 2 nuts and 2 clips while tightening them to 7.0 N.m (70 kgf.cm, 62 in.lbf).
