the code is for fuel pressure above max limit. the two things to check are the fuel control actuator and fuel pressure sensor. You check the actuator by cycling the key on then back off and you should hear the actuator click when key is turned off. If you dont hear it , that means it is stuck. Next would be the fuel pressure sensor, but without access to a scan tool it is going to be hard to test this.
