Removal and Installation
WARNING:
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
NOTE:
Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or tubes.
NOTE:
When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube.
- Disconnect the battery ground cable. For additional information, refer to BATTERY, MOUNTING AND CABLES article.
- Release the fuel system pressure. For additional information, refer to FUEL SYSTEM - GENERAL INFORMATION article.
- Remove the Air Cleaner (ACL) outlet pipe. For additional information, refer to INTAKE AIR DISTRIBUTION & FILTERING article.
- Disconnect the crankcase ventilation tube quick connect coupling from the ACL outlet pipe-to-Throttle Body (TB) adapter. For additional information, refer to FUEL SYSTEM - GENERAL INFORMATION article.
- Release the clamp and remove the bolt and the air intake resonator assembly.
- To install, tighten to 10 Nm (89 lb-in).
- Remove the 3 ACL
outlet pipe-to- TB
adapter bolts.
- To install, tighten to 10 Nm (89 lb-in).
- Remove the ACL outlet pipe-to- TB adapter.
- Disconnect the Electronic Throttle Control (ETC) electrical connector.
- Disconnect the Throttle Position (TP) sensor electrical connector.
- Disconnect the Evaporative Emission (EVAP) tube quick connect coupling from the intake manifold. For additional information, refer to FUEL SYSTEM - GENERAL INFORMATION article.
- Disconnect the heated PCV intake fitting electrical connector. For additional information, refer to FUEL SYSTEM - GENERAL INFORMATION article.
- Disconnect the fuel tube quick connect coupling. For additional information, refer to FUEL SYSTEM - GENERAL INFORMATION article.
- Disconnect the 8 fuel injector electrical connectors.
- Remove the 4 fuel rail bolts and the fuel rail and injectors as an assembly.
- To install, tighten to 10 Nm (89 lb-in).
- Remove the fuel injector-to-fuel rail locks and separate the 8 fuel injectors from the fuel rail.
- Discard the upper and lower fuel injector O-ring seals.
- To install, reverse the removal procedure.
NOTE:
Use O-ring seals that are made of special fuel-resistant material. Use of ordinary O-rings can cause the fuel system to leak.
NOTE:
Lubricate the new O-ring seals with clean engine oil prior to installation.
