• Q: How to service and repair the fuel injector on 2003 Toyota Echo?

  A: Start the repair process of the fuel injector by first taking off the No.2 cylinder head cover and then the cylinder head cover. You must disconnect the fuel tube through two steps starting with fuel pipe clamp removal then separating the fuel tube connector from the fuel pipe. Always take caution due to remaining fuel pressure in the line. The first step requires the removal of both the injectors and delivery pipe after disconnecting the 4 injector connectors and unfastening a total of 3 bolts to extract the delivery pipe and its attached 4 injectors and fuel pipe followed by taking out the 2 cylinder head spacers. Remove the 4 injectors from the delivery pipe while carefully extracting them. Do not overlook the necessary step of removing O-rings and grommets from each injector. New grommets must be applied to each injector before coating their O-rings with spindle oil or gasoline and applying the solution to the delivery pipe contact points. Secure the 4 injectors in place by turning motion followed by insertion into delivery pipes with their connectors at the external surface. Secure the 2 spacers against the cylinder head before applying spindle oil or gasoline to the grommet points and placing delivery pipe and fuel pipe with installed injectors onto the cylinder head. Test the delivery pipe bolts and fuel pipe bolt while observing smooth injector rotation before changing the O-ring. Fasten both delivery pipe bolts to 19 N.m of torque (190 kgf.cm, 14 ft.lbf) and the fuel pipe bolt to 9.0 N.m (92 kgf.cm, 80 in.lbf). Install the fuel tube to the fuel pipe by following proper connection precautions then secure the fuel pipe clamp into position. After attaching the wire harness protector cover with its bolt and two nuts you can install the PCV hose to the cylinder head cover. Last in the procedure is to attach the high-tension cords to the ignition coils. The fuel delivery pipe disconnect requires Special Service Tool 09268-21010 for connector connection while you remove the fuel pipe clamp then extract the fuel tube assembly's metallic connector. To detach and protect the fuel tube connector users must first disengage the fuel pipe clamp followed by connector cleaning then disconnect it manually and must provide protection against further damage or pollution.
