Andy.B1971 Posted October 28, 2014 Share Posted October 28, 2014 Low fuel rail pressure usually indicated a new fuel filter is needed. Under light throttle the car/van will run fine but as soon as you give it the go pedal it cuts out as fuel cannot get through quick enough. Regular fuel filter changes are a must and a quality one too. :D :D :driving: 1 Quote Link to comment Share on other sites More sharing options...

farriervan2390 Posted October 29, 2014 Author Share Posted October 29, 2014 Ill change it again and see if that makes any differene thanks, is it possible there could be a nlockage further down, or the pump ouldnt be running corectley like I said the obd just said low rail pressure, just thinkimg because it startsand drives sweet you cant turn these pumps p can you ?? Like older ones, thanks for your help Quote Link to comment Share on other sites More sharing options...
