General Information

The engines covered by this guide employ a Multi-Port Fuel Injection (MFI) system. The MFI system injects fuel into the intake manifold above the intake valve port of each cylinder through separate injectors.

The fuel system consists of the fuel tank, electric fuel pump, fuel filter, fuel tubes, fuel hoses, vacuum hoses, throttle body, and the fuel injectors.

A fuel return system is used on all vehicles. The system consists of the fuel tubes and hoses that route fuel back to the fuel tank.

The fuel tank assembly consists of the tank, filler vent tube, a fuel gauge sending unit/fuel pump assembly, and a roll over valve.

Another part of the fuel system is the evaporation control system, which is designed to reduce the emission of fuel vapors into the atmosphere. The description and function of the evaporative control system is found in Driveability & Emissions Controls .

To perform most of the fuel injection testing or servicing, you will need a DRB III or equivalent scan tool.
