Fuel System - General Information

Fuel System

The fuel system consists of the:

- L-shaped fuel tank.
- Fuel Pump (FP) module.
- FP control module.
- Easy Fuel(TM) (capless) fuel tank filler pipe assembly.
- Inertia Fuel Shutoff (IFS) switch.
- fuel tubes (liquid and vapor).
- fuel injectors.
- fuel rail.
- Fuel Tank Pressure (FTP) sensor (part of the fuel vapor tube assembly).

The vehicle:

- uses a 2-speed Mechanical Returnless Fuel System (MRFS).
- uses a standard (L-shaped) fuel tank.
- has a FP module that supplies fuel under pressure to the fuel rail.
- has a lifetime fuel filter (serviced as part of the FP module).
- has a serviceable fuel level sender mounted on the FP module.
- has an Easy Fuel(TM) (capless) fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by the installation of a new fuel tank filler pipe assembly.
- has a supplemental refueling adapter, located behind RR quarter trim access panel.
- has a FP module that operates on 10 or 12 volts depending on load, that supplies fuel under pressure to the fuel rail.
- has a FP control module located behind the fuel tank, mounted to the underside of the vehicle.
- has an IFS switch located behind the RH cowl trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- is equipped with a sequential Multi-Port Fuel Injection (MFI) system.
- uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold.
- fuel injectors are supplied with pressurized fuel from the FP module to the fuel rail.
- fuel injection rail pressure is controlled by the electronic FP module which is enabled by the PCM.



Fuel Pump (FP) Shut-off Feature

In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump (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 shut off the FP module.

Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by resetting the IFS switch located behind the RH cowl trim panel.
