Fuel System

Fuel System

The fuel system consists of the:

- saddle-type fuel tank.
- Fuel Pump (FP) module.
- FP control module.
- Easy Fuel(TM) (capless) fuel tank filler pipe assembly.
- fuel level sensor assembly.
- fuel level sender (mounted on the FP and the fuel level sensor assembly).
- fuel tubes.
- 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 dual-container (saddle-type) 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 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 in the spare tire compartment.
- 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 RH C-pillar trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- 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.
- has a serviceable fuel level sender mounted on the FP module.
- has a serviceable fuel level sender mounted on the fuel level sensor assembly.


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.

Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by first turning the ignition to the OFF position and then turn the ignition to the ON position. In some instances the vehicle may not start the first time and may take one additional ignition cycle.
