How to replace the fuel injector assembly on 2002 Toyota Camry?

Question

Accepted Answer

The first step to exchange the fuel injector assembly should focus on gasoline leakage prevention. Begin the replacement process by first removing the air cleaner cap together with its hose and then uninstalling the engine cover sub-assy No.1. Cut the fuel tube sub-assy connection while removing the fuel delivery pipe and injector unit properly to avoid letting injectors fall. The first step requires removing ventilation hose No.2 then disconnecting the four injector connectors before removing the two clamps and wire harness on the delivery pipe. The following procedure involves the removal of delivery pipe together with four injectors by disassembling the two bolt connections. Then detach the two spacers contained within the cylinder head. You should start by extracting the four injectors from the delivery pipe to perform new fuel injector assembly installation. Before placing each injector insulator you should apply spindle oil or gasoline to the new O-ring and then install it before placing the injector onto its delivery tube. A thin layer of spindle oil or gasoline should be applied to both the delivery pipe area and O-ring. Follow this process when installing the four injectors by pushing them into delivery pipes with clockwise and counterclockwise turns yet avoid twisting O-rings and verify injector movement is smooth; replace any injector that does not turn properly with a new O-ring. Position the injector connectors downward. Position the delivery pipe first by placing two spacers onto the cylinder head and afterwards installing it with four injectors. Check that the delivery pipe injectors rotate freely after temporarily installing the two bolts which maintain the delivery pipe position. If the injectors do not rotate smoothly it indicates a possible O-ring misinstallation that requires replacement. The delivery pipe should sit on the cylinder head where the injector connectors face outward before tightening two bolts to 20 N.m (204 kgf.cm, 15 ft.lbf). Conduct a final inspection for fuel leakages.
