Fuel System

The fuel system consists of:

The vehicle is equipped with electronic multi-port fuel injection that is supplied by an electronic returnless fuel system. The PCM receives pressure information from a fuel pressure sensor mounted on the fuel rail. The PCM is able to maintain constant fuel pressure by varying the FP output. This is accomplished by increasing or decreasing voltage supplied to the FP. The returnless fuel system offers improved economy, lower fuel temperatures and decreased fuel vapor in the fuel tank.
