@vadford2007 remember that there are a few causes of this error code. So you do want to make sure that you check all of it:
Faulty Rail Pressure (FRP) Sensor
FRP harness is open or shorted
FRP circuit poor electrical connection
Faulty Fuel Pump
Faulty Fuel Filter
The FRP sensor is located top center of the fuel rail to the injectors. It has a wiring plug and a vacuum line connected to it. If you post some images of your engine, I am certain we can point it out for you. To replace it, you should always first release the pressure on the fuel line. You can accomplish this by removing the Fuel Pump (FP) control module fuse in your fuse box. Then start the engine and allow it to idle until it stalls. Once it stalls you can try to crank it over a couple of times for any residual pressure. Disconnect your battery (make sure that you have a radio code just in case your vehicles radio needs it) Unplug your vacuum line and your electrical plug. Then use a wrench to remove the sensor....
