mat2495 Posted December 27, 2010 Share Posted December 27, 2010 Hi all, i have a little problem I hope some one can help with. I have just replaced the chassis on my 200td1 90, and having put it back together im getting fueling problems, as soon as the engine is turned off fuel runs back into the tank down the return line. This causes poor starting. I replaced the injector spill pipes, as they were split, but the problem is still there. The other thing is that as soon as my fuel gauge drops below 1/4 of a tank remaining the car runs a bit rough, specifically when reducing engine speed to idle i.e when changing gear etc, at this point it nearly stalls. it feels like fuel starvation to me but i may be barking up the wrong tree, just seems that the timing with the fuel gauge is too much to be a coincidence. topping the tank up fixes this problem also. Any thoughts or suggestions appreciated. Thanks, Matt Quote Link to comment Share on other sites More sharing options...
Frax Posted December 27, 2010 Share Posted December 27, 2010 I have not had the fuel sender/pick up pipe off on a 200tdi but I do know that some are fitted with an NRV which if it has one may be faulty, some have also a filter on the end that could be blocked. Also look at lift pump. Just a thought. Frax Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted December 27, 2010 Share Posted December 27, 2010 as soon as the engine is turned off fuel runs back into the tank down the return line. This causes poor starting. I don't see how an empty return line would cause poor starting? How old is the lift pump? Quote Link to comment Share on other sites More sharing options...
mat2495 Posted December 28, 2010 Author Share Posted December 28, 2010 i presumed it was draining the injectors. lift pump is new but was a pattern part. is it worth replacing with something like a delphi unit? ill pull the pick up unit out of the tank and have a look. Thanks for all the ideas Quote Link to comment Share on other sites More sharing options...
