Hi my 2005 skoda fabia vrs 1.9tdi pd130 is displaying fault code P0230 (fuel pump primary circuit malfunciton). I have replaced the fuel pump, the relay, the lift pump and the vacuum box. The code still appears, when I reset it it will come back on after a few miles drive going up and down gears and then goes into limp home mode. Any ideas would be appreciated.....thanks in advance

could be wireing TO the relay  from ECU?    (no diagram to hand at the mo')
