2010 fabia 1.2 HTP. cranks but wont start, runs briefly (seconds) with easy start. new ecu coded to vehicle including immo . no fault codes showing on OBD scanner. not immo problem as immo lamp would remain on and an immo related fault code present. suspect fuelling problems as cant hear fuel pump running and no volts present on the two thick wires on the fuel pump connector on the fuel pump access panel under the back seat. thick wires are brown (pin 5) and blue/white (pin 1), presume these are for the fuel pump not the sender. ? checked relevant fuses. relays not in end of dash position as relay info (online) suggests they are/ should be , but under the dash above the fuses. could someone pls confirm fuel pump relay position, and part number for new one would be helpful. happy to try a pin compatible cheap/ generic one if I can find out which one it is and pin configuration. it has also been suggested to check the main engine control relay, wherever that is ? wiring diag would be good also, if available. many thanks all !
