REMOVAL AND INSTALLATION


caution When the fuel injector replacement is performed, idling speed may be unstable because the MPI engine learning is not completed. To make it stable, make the system learn the idling (Refer to GROUP 00, Precautions before Service - Learning Procedure for Idling in MPI Engine ).
Pre-removal Operation
  • Fuel Line Pressure Reduction (Refer to ).
  • Strut Tower Bar Removal (Refer to GROUP 42, Strut Tower Bar ).
  • Engine Cover Removal (Refer to GROUP 11E, Camshaft and Valve Stem Seal ).
  • Air Cleaner Intake Duct, Air Cleaner Assembly and Air Cleaner Duct Assembly Removal (Refer to GROUP 15, Air Cleaner ).
  • Air Pipe B Removal (Refer to GROUP 15, Intercooler ).

 Post-installation Operation
  • Air Pipe B Installation (Refer to GROUP 15, Intercooler ).
  • Air Cleaner Intake Duct, Air Cleaner Assembly and Air Cleaner Duct Assembly Installation (Refer to GROUP 15, Air Cleaner ).
  • Engine Cover Installation (Refer to GROUP 11E, Camshaft and Valve Stem Seal ).
  • Strut Tower Bar Installation (Refer to GROUP 42, Strut Tower Bar ).
  • Fuel Leakage Inspection.

REMOVAL SERVICE POINTS

<<A>> FUEL MAIN PIPE DISCONNECTION

Raise the retainer, and pull out the fuel main pipe.
note If the retainer comes off, install it securely after pulling out the fuel main pipe.

<<B>> FUEL DELIVERY PIPE AND FUEL INJECTOR ASSEMBLY REMOVAL
caution Do not drop the fuel injector.
Remove the fuel delivery pipe with the fuel injector assembly attached to it.

INSTALLATION SERVICE POINTS

>>A<< FUEL INJECTOR ASSEMBLY/FUEL PRESSURE REGULATOR INSTALLATION
1.
caution Do not let the engine oil get into the fuel delivery pipe will be damaged.
Apply a drop of new engine oil to the O-ring.
2.Turn the fuel injector assembly and fuel pressure regulator to the right and left to install to the fuel delivery pipe. Be careful not to damage the O-ring. After installing, check that the item turns smoothly.
3.If it does not turn smoothly, the O-ring may be trapped, remove the item, re-install it into the fuel delivery pipe and check again.
4.Tighten the fuel pressure regulator to the specified torque.
Tightening torque: 12 ± 1 N·m

>>B<< FUEL DELIVERY PIPE AND FUEL INJECTOR ASSEMBLY INSTALLATION
caution Securely bring the insulator into contact with the injector to prevent air leak from the insulator area.

Be sure that there is no clearance between the insulator area and the injector, and install them to the cylinder head.

>>C<< FUEL MAIN PIPE CONNECTION

caution After connecting the fuel main pipe, check that it has been securely installed by slightly pulling in the removal direction. At this time, also check that there is approximately 3-mm play.
