I am getting a continuous error code saying that my fuel pressure is too low and this is a faulty fuel pressure regulator . I thought the fuel pump just pressurized the fuel and that was it. I have searched the area of the fuel rail and I can't find anything. Is it in the fuel pump itself ? Why would it be sending a code that pressure is too low? The car drives well but has a history of occasionally dogging. The problem vanishes when the car is allowed to sit for a few minutes but this happens when the tank is low and I know I have far less gas than the gauge indicates. One other error code is present but I write that one off, troubled ambient temperature sensor. So where is this fuel pressure regulator?
