Fuel System - General Information

FUEL SYSTEM

WARNING:
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and can be ignited, resulting in possible personal injury.
- Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.

The fuel system consists of the following:
- Fuel tank.
- Fuel tank filler pipe.
- Fuel pump module.
- Fuel transfer jet pump.
- Fuel lines.
- Fuel filter.
- Fuel injectors.
- Fuel rail.
- Fuel tank pressure transducer.
- Inertia fuel shutoff (IFS) switch.
- Fuel injection pressure temperature sensor.

The vehicle:
- uses an electronic returnless fuel system.
- has a dual-container (saddle-type) fuel tank, each half with a fuel level sensor.
- has a fuel transfer jet pump in the right fuel tank half, to supply fuel from the left side to the right side. This jet pump contains the fuel pump module that supplies fuel under pressure to the fuel rail.
- has a fuel filter located on the passenger side in front of the fuel tank.
- is equipped with a sequential multiport 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 fuel transfer pump through the fuel pump module to the fuel rail.
- fuel injection rail pressure is controlled by the electronic fuel delivery module which is enabled by the powertrain control module (PCM).
- has a fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by installation of a new filler pipe assembly.
- has a fuel injection pressure sensor, which monitors the fuel pressure during running and key on/engine off conditions.
- has an inertia fuel shutoff (IFS) switch located in the passenger side footwell that shuts off fuel in the event of a collision.
