Re: Ford auto mechanic?
Usually pressure is not modulated at all. The fuel pump is full on while a regulator regulates to the pressure (which is usually unchanging). This leads me to believe that it's not the fuel pump. The thing that would be change fuel to the engine is fuel injectors that are controlled by the ECU (engine Control Unit). If you're looking for data output from that, an OBD2 sensor is something that mechanics use to diagnose the car. Hope this helps
