I have a 2003 Ford Fiesta Finesse, 1.3, 8 valve Duratec. I parked it up at 10pm, returned at 10.45pm and car would not start. Turing ignition on I get seat belt light, door open light and oil light and thats all. No engine management, brake or anything else. I noticed at the time that the rev counter needle was flickering and the petrol gauge and speedo were also flickering, with ignition key out. Tried spare key, same. tried new battery, same. Had to call RAC they couldn't find anything and suggested it could be ECU. I don't think it is though. Has anyone any ideas?
