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

  A: The starting point for fixing the fuel injector involves taking off the No.2 cylinder head cover and cylinder head cover. In order to disconnect the fuel tube the technician must remove the fuel pipe clamp alongside disconnecting the fuel tube connector from the fuel pipe while taking necessary precautions due to retained pressure in the fuel pipe line to prevent splashing. The service process begins by disconnecting four injector connectors as well as three bolts to separate the delivery pipe with its attached fuel pipe while also separating the 4 injectors. After that, two spacers must be removed from the cylinder head. When removing injectors from the delivery pipe users should handle them with care while taking out their accompanying O-rings as well as grommets from each injector. Start by placing new grommets on each injector followed by applying spindle oil or gasoline lightly on new O-rings and the delivery pipe contact zone with O-rings. Install the 4 injectors while turning them clockwise while pushing them into delivery pipes and verify that injector connectors should face outward direction. Install the 2 spacers onto the cylinder head before applying spindle oil or gasoline to grommet areas of delivery pipe and fuel pipe with 4 injectors attached to it. The delivery pipe and fuel pipe bolts should be installed briefly to verify simple rotation; any obstacles in rotation require O-ring replacement. Use the specified torques when securing delivery pipe bolts at 19 N.m (190 kgf.cm, 14 ft.lbf) and fuel pipe bolts at 9.0 N.m (92 kgf.cm, 80 in.lbf). Fasten the fuel tube connector to the fuel pipe while following safe connection procedures and install the fuel pipe clamp. You must install the wire harness protector cover by securing it with a bolt and 2 nuts while linking the PCV hose to the cylinder head cover and high-tension cords to Ignition Coils.
