FUEL SYSTEMWARNING:
- Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious 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 component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
The fuel system consists of the following components:
- Fuel filter
- Fuel injectors
- Fuel pump (FP) module
- Fuel rail
- Fuel rail pressure and temperature sensor
- Fuel tank
- Fuel tank filler cap
- Fuel tank filler pipe
- Fuel tank pressure (FTP) sensor
- Fuel tubes (liquid and vapor)
- Inertia fuel shutoff (IFS) switch
The vehicle:
- is equipped with a sequential multi-port fuel injection (MFI) system.
- uses separately controlled fuel injectors mounted to the intake manifold for each cylinder.
- has a FP module that supplies fuel under pressure to the fuel rail.
- has fuel tubes (liquid and vapor) mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- 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.
- has a fuel rail which is equipped with a fuel rail pressure and temperature sensor.
- fuel injection rail pressure is controlled by the electronic FP module which is enabled by the PCM.
- has a 1/4 turn vented type fuel tank filler cap.
- has a fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by installation of a new fuel tank filler pipe assembly.
- has an IFS switch located in the passenger side footwell that shuts off fuel in the event of a collision.
