Fuel System - General Information

FUEL SYSTEM

The fuel system consists of the following components:
- fuel filter
- fuel injectors
- fuel level sensor and pump
- fuel supply manifold
- fuel tank
- inertia fuel shutoff (IFS) switch
- fuel injection pressure sensor

WARNING: The evaporative emission system contains fuel vapor and condensed fuel vapor. Although not present in large quantities, it still presents the danger of explosion or fire. Disconnect the battery ground cable from the battery to minimize the possibility of an electrical spark occuring, possibly causing a fire or explosion if fuel vapor or fuel liquid is present in the area. Failure to follow these instructions may result in personal injury.

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 may be ignited, resulting in possible personal injury.

WARNING: 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 present and may be ignited. Failure to follow these instructions can result in personal injuries.

The vehicle:

- uses an electronic returnless fuel system.
- is equipped with a sequential multiport fuel injection (MFI) system.
- has a fuel injection supply manifold.
- 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 pump through the fuel injection supply manifold.
- has a fuel tank filler pipe assembly which cannot be modified in any way and is serviced only by replacement with a new filler pipe assembly.
- has a fuel injection pressure sensor which monitors the fuel pressure during running and key on/engine off conditions.
