Fuel System




Fuel System

The fuel system consists of the following:

- Fuel rail
- Fuel injectors
- Fuel tank
- Fuel Pump (FP) module (located in the fuel tank)
- Fuel supply tube
- Easy Fuel(TM) (capless) fuel tank filler pipe assembly (which cannot be modified)
- Lifetime fuel filter (serviced as part of the FP module)
- Supplemental refueling adapter located in the spare tire compartment
- 2-speed Mechanical Returnless Fuel System (MRFS)

The vehicle is equipped with a Multi-Port Fuel Injection (MFI) system.

Fuel delivery is accomplished through a MRFS.

- The FP supplies the fuel injectors with pressurized fuel through the fuel rail.
- The fuel injectors are separately controlled and mounted to the intake manifold for each cylinder.
- The fuel tubes route the fuel from the fuel pump to the fuel rail.
- The fuel filter cleans the fuel delivered from the FP to the fuel rail.

Fuel Pump (FP) Shut-off Feature

In the event of a moderate to severe collision, the vehicle is equipped with a FP shut-off feature that is initiated by the event notification signal.

The event notification signal is a signal provided by the Restraints Control Module (RCM) to the FP control module. Signal communication between the RCM and the FP control module allows the PCM to initiate secondary fuel cut off to shut off the FP.

Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by resetting the Inertia Fuel Shutoff (IFS) switch located behind LH rear quarter trim panel access cover.
