Important: 

1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .



2. Disconnect the four spark plug wires from the two ignition coils.
3. Disconnect the PCV and breather hoses from the valve cover.
4. Remove the nut and the accelerator cable bracket from the cylinder head.



5. Remove the two nuts (1) from the wire harness cover plate.
6. Remove the one bolt (2) and wire harness cover plate (3) from the engine.



7. Disconnect the 4 fuel injector electrical connectors (1).
8. Remove the two bolts (2) and pull back the wiring harness (3).
9. Remove the fuel feed hose quick connect coupling cover.



10. Disconnect the fuel feed hose quick connect fitting from the fuel feed pipe of the fuel rail using the J 43178 Prizm Fuel Line Quick Connect Separator. Use a shop towel to catch any remaining fuel that may leak. Refer to Metal Collar Quick Connect Fitting Service .



11. Remove the one fuel rail inlet pipe hold down bolt (1).



12. Remove the two fuel rail hold down bolts (1).
13. Remove the fuel rail (6) with the fuel injectors from the cylinder head.
14. Remove the two fuel rail spacers (2) from the cylinder head.
15. Remove the fuel injectors (4) with O-ring (5) and grommet (3) from the fuel rail.

Important: Replace the fuel injector O-rings when servicing the fuel injectors. Take care not to damage the O-rings during installation.

1. Install the fuel injectors (4) and grommets (3) with new O-rings (5) to the fuel rail.
2. Install the fuel rail spacers (2) to the cylinder head.

Important: Make sure that the fuel injectors rotate smoothly. Check for incorrectly installed fuel injector O-rings and replace the O-rings if necessary.

3. Install the fuel rail (6) with the fuel injectors to the cylinder head.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Secure the fuel rail (6) with the two fuel rail bolts (1).
