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