• Q: How to install the fuel injector assembly on 2009 Toyota Tacoma?

  A: Before installing the fuel injector assembly you must apply gasoline or spindle oil to new O-rings then place the rings onto each fuel injector. Before mounting the fuel delivery pipe with fuel injector, apply gasoline or spindle oil lightly to the contact areas of the delivery pipe and injector O-ring. Then repeat the oil application to the O-ring before fitting it onto the delivery pipe by rotating it correctly to ensure the O-ring remains unbent and undamaged. The fuel injector must rotate flawlessly during this check. If there is any resistance to rotation then you should replace the O-ring. The procedure requires light application of gasoline or spindle oil onto new O-rings before installing them on delivery pipe spacers before proceeding to place 4 vibration insulators on the cylinder head surface and the 2 delivery pipe No. 1 spacers. Install the fuel delivery pipe with its 4 fuel injectors then provisionally tighten the 2 bolts but maintain the fuel injectors from dropping. Before finally tightening the 2 bolts use the torque wrench to set them at 12 Nm (122 kgf-cm, 9 ft-lbf). Install the harness clamp bracket with its bolt torqued to 8.2 Nm while you connect the wire harness clamp with the compressor magnetic clutch connector (with air conditioning) and engine wire harness clamp and VSV connector and 4 injector connectors. Before checking the connection by pulling the fuel hose connector and pipe, make sure to check for scratches and foreign objects on both pieces while you push down the checker of the fuel hose. Align the fuel hose connector with the pipe stem and then push the connector into the stem until the retainer clicks. Rephrase this step for achieving the same result with fuel hose No. 2. The throttle assembly with motor body needs installation along with the intake air connector while the cable must have a torque connection at the negative battery terminal set at 3.9 Nm (40 kgf-cm, 35 in-lbf). The maintenance process requires engine coolant addition to check for leakage and fuel leakage. The vehicle needs the engine under cover sub-assembly No.1 to be put into position last in this process.
