Technically, it can mean that either the fuel pressure is too high or there is a problem with the signal from the fuel . Not only that, if the fuel pressure sensor is faulty, it may output too little information to the ECU, which in turn may increase the amount of fuel being fed into the engine. The fuel rail pressure sensor is located on the fuel rail, which is often located near or under the intake manifold. Hi Magnus, 2007 Ford F150, crank no start. Also, the pump has a "Fuel Pump Driver Module" in the trunk, on the driver's rear wheel well, inside the trunk. There may also be an increase in fuel consumption, which can be costly. In most cases, this will be an electrical issue with the fuel rail pressure sensor or its wiring. This includes the sensor itself, its connector, and the wiring that goes to the ECU.
