Scheme 42: Description and Operation

The electronic returnless fuel system utilized has the advantages of reduced fuel tank vapor, requires less electrical power and does not require a fuel return line.

Fuel is supplied at high pressure to the injectors via a fuel rail which incorporates six fuel injectors, a fuel pressure and a fuel temperature sensor. The PCM increases the fuel pressure to minimize fuel vapor formation to maintain fuel flow across the injectors.

A pressure relief valve is fitted to the fuel rail at the front of the camshaft cover. This valve allows the fuel system to be depressurized during servicing.
