i own a remapped 2006 fabia vrs , i recently plugged in OBD 2 fault code reader and it came up with 2 codes . One was for the camshaft sensor and the other code said fuel pump not earthed. When car cut out the first time i changed camshft sensor and away she went . 2 weeks later the same code came up and its cutting out again. Engine management light comes on one day and its off the next . its doing my head in . Havent a clue whats going on , when its cutting out it shudders to a stop . Is it the fuel pump thats causing problems ? HELP anyone. cheers

Fuel pump relay.
