WARNING:
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.
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 component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
The fuel system consists of the:
- standard fuel tank.
- fuel lines.
- fuel filter providing filtration to protect the fuel injectors from foreign material.
- 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 tank.
- 1/4 turn-type fuel tank filler cap.
- inertia fuel shutoff (IFS) switch.
- fuel pump (FP) module containing:
- the electric FP module which provides pressurized fuel to the engine.
- the fuel level sensor.
- a check valve which maintains system pressure after the FP module is shut off.
- a pressure relief for overpressure protection.
The fuel pump is controlled by the PCM. Electrical power to the pump is provided through the IFS switch located under the right front kick panel.
