hi there.had my car a couple of months now and its been a dream til now.i was pulling away from a junction and the engine cut out without warning.i waited a few minutes before starting the car again which took about 15seconds of turning over to start (unusual)got home ok without cutting out.i had to go out a couple of hours later but got as far as a couple of hundred yards and it cut out again.i got it going again turned back and came home.can anyone help me with my problem,could it be the fuel filter?
Check the lift pump in tank is giving fuel,it will run when engine cold and glow plugs on,it can still buzz and work but not give hardly any fuel.It will not pump on hot starts (which is why you need to crank engine a bit)and when engine is running the ecu switches it off and on as needed/determined by a pressure switch on the filter head.Second scenario is your fuel level is at a 1/4 tank and the 'o' ring that seals lift pump in cradle is letting air in,a common fault on the tds,just google lift pump 'o' ring and lots of info about it.If it is 'o' ring you can just keep tank above 1/2 full and have no problem with it,giving you time to get it sorted another day.If you find lift pump is shot and they are famous for it,just replaced mine after it done 40k from new with a facet,google again 'replacing lift pump with facet' nice post on vegetableoildiesel.co.uk with picture guide through on how to fit and wire up.My last lift pump from gsf was £120, a facet is under £40
