hi m8 i have a v reg 2.5v6 mondeo that had an intermittent prob it wouldnt start! turn ign on if fuel pump goes car will turn over and start
if i dont hear pump car wont turn over to start!!!
if it wont pump/turn over i leave ign sw on and wait!!! (Well up to the other day that is) after waitin i rtn to the car hear the fuel pump going I know the car will start and has never missed a beat when running!! (seems to be the longer I leave it the longer I wait ie; long wait in morn, drive to paper shop 500yards away car starts on the button leave in car park all day long wait,,use it at dinner time short wait???)
i hav bridged fuel pump relay(pumps)i have bridged starter relay(turns over) but still wont start whats missing is an earth signal from the ecu to turn everything on and allow to start suspect alarm ecu ,engine ecu or poss bad earth! The other day after waitin about an hour!! Car started and I started home 70 mls got 5mls and car started to mess about something elec poss a relay was cutting/pulsing in and out fast (but could not hear it and never have!)came to a holt,tried to start was ok got 500 yards car rtns to jerkin/pulsing to this cutting in and out
everything was cutting/pulsing in and out, alarm light fuel pump fuel pump relay (changed( still the same)) heater stopped blowin so turned to relays wiring etc wriggled everything inc under dash no change turned ign off waited turned on no flashing lights pulseing fuel pump waited 45 mins fuel pump came on started car got home with no prob 80 90 mph But has not started since I have left ign on all day and still fuel pump wont cut in and car wont turn over do you hav any ideas about prob
thanks fletch
