Fuel System

Fuel System

The fuel system consists of the:

- 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 serviceable fuel level sender mounted on the FP module.
- 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 one-fourth turn vented type fuel tank filler cap.
- has a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- has a fuel tank filler pipe check valve that prevents spitback during refueling.
- has an IFS switch located in the passenger side footwell that shuts off fuel in the event of a collision.
