Fuel System - General Information

Fuel System

The fuel system consists of the:

- L-shaped fuel tank.

- Fuel Pump (FP) module.

- FP (Fuel Pump) 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 (Fuel Pump) module that supplies fuel under pressure to the fuel rail.

- has a lifetime fuel filter (serviced as part of the FP (Fuel Pump) module).

- has a serviceable fuel level sender mounted on the FP (Fuel Pump) 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 (Fuel Pump) module that operates on 10 or 12 volts depending on load, that supplies fuel under pressure to the fuel rail.

- has a FP (Fuel Pump) control module located behind the fuel tank, mounted to the underside of the vehicle.

- has an IFS (Inertia Fuel Shutoff) 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 (Fuel Tank Pressure) 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 (Fuel Pump) module to the fuel rail.

- fuel injection rail pressure is controlled by the electronic FP (Fuel Pump) 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 (Fuel Pump) control module. Signal communication between the RCM (Restraints Control Module) and the FP (Fuel Pump) control module allows the PCM to shut off the FP (Fuel Pump) module.

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