Fuel Delivery and Air Induction: Description and Operation

FUEL DELIVERY SYSTEM
The front wheel drive car uses a plastic fuel tank located rear center of the vehicle.

The Fuel Delivery System consists of the following items:
- Electric fuel pump module
- Fuel filter
- Tubes/lines/hoses
- Fuel injectors

The in-tank fuel pump module contains the fuel pump. The pump is serviced as part of the fuel pump module. Refer to Fuel Pump Module.

The fuel filter is replaceable only as part of the fuel pump module.

FFV REPLACEMENT PARTS
Many components in a Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that the vehicle is serviced with correct ethanol compatible parts.

CAUTION: Replacing fuel system components with non-ethanol compatible components can damage your vehicle and may void the warranty.

The fuel system provides fuel pressure by an in-tank pump module. The PCM controls the operation of the fuel system by providing battery voltage to the fuel pump through the fuel pump relay. The PCM requires only three inputs and a good ground to operate the fuel pump relay. The three inputs are:
- Ignition voltage
- Crankshaft Position (CKP) sensor
- Camshaft Position (CMP) sensor
