Fuel System - Overview

WARNING: This page is about a different variant/trim than selected.

Overview

The fuel system:

is a variable speed Closed Loop Pressure Control (CLPC) Fuel System with Gasoline Turbocharged Direct Injection (GTDI).
uses a dual-container (saddle-type) fuel tank.
has a non-serviceable integrated fuel level sensor module, molded inside the fuel tank.
has a in tank Fuel Pump (FP) that supplies fuel under pressure to the high pressure fuel pump.
if equipped, 3.0L - AWD has 2 in tank Fuel Pumps (FP) and 3.0L - FWD has one in tank Fuel Pumps (FP) that supply fuel under pressure to the high pressure fuel pump.
has an Easy Fuel™ (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 luggage compartment.
has a high pressure fuel pump that supplies high pressure, low volume fuel pressure to the fuel rails.
3.0L - AWD has 2 FPDM and 3.0L - FWD has one FPDM located on the driver's side lower "C" pillar area.
has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold and are supplied with pressurized fuel from the high pressure fuel pump through the fuel rail.
fuel rail pressure is controlled by the electronic FP module which is enabled by the PCM.
has a serviceable fuel level sender mounted on the Fuel Pump Module.
3.0L - AWD has a serviceable external in-line fuel filter.

Fuel Pump Shut-off Feature

NOTE: Refer to the Description and Operation, Intelligent Access with Push Button Start in to review the procedures for achieving the various ignition states (ignition OFF, ignition in ACCESSORY, ignition ON and ignition START) on vehicles with this feature.

The event notification feature provides other vehicle subsystems with information pertaining to SRS deployment or fuel cutoff status. When an impact occurs which exceeds a pre-determined threshold, the RCM sends a signal on a dedicated circuit to the BCM.

When the BCM receives a crash signal input from the RCM, the BCM initiates fuel cutoff by removing the ground signal from the Fuel Pump Relay and also sends a signal to the PCM on a dedicated circuit, disabling the fuel system.

After the fuel system is disabled, the vehicle can be re-started after carrying out the following steps:

Turn the ignition OFF.
Turn the ignition to START (on vehicles with push button start, press the start/stop button while the brake pedal is pressed).
Turn the ignition OFF.
Turn the ignition ON.
