Crofter Posted February 18, 2015 Share Posted February 18, 2015 I have a Land Rover 90 fitted with a Disco 200TDI, until the other day this went well and pulled great , but the other day I was towing my trailer and went to overtake a car as I was passing the car I heard a noise and seemed to loose power, the noise was maybe the trailer. Now it's not pulling when climbing hills or even on the flat, ten acceleration is poor although there's not much smoke, anyone got an idea what's wrong. I have taken the pipe from the inter cooler to manifold off and there's a Good blow from it so I think the turbo is ok. Could it be the injector pump diaphragm?

LiamC Posted February 18, 2015 Share Posted February 18, 2015 First thing I would check for is fuel starvation or air in the fuel. Check joints in the pipework and check the lift pump. Quote Link to comment Share on other sites More sharing options...
reb78 Posted February 18, 2015 Share Posted February 18, 2015 Lift pump failed perhaps? Quote Link to comment Share on other sites More sharing options...
Yostumpy Posted February 18, 2015 Share Posted February 18, 2015 check air filters not blocked check all intercooler hoses, for split or collapse fit new fuel filter check lift pump ( some have small screw on top, to gain access to a gauze filter that gets blocked) check fuel filler cap vent , not blocked.

Snagger Posted February 18, 2015 Share Posted February 18, 2015 Has the boost pipe from the turbo the the injection pump failed or popped off? That would prevent the fuelling responding to boost, so no black smoke but a big performance drop, with no other noises or symptoms other than initial gush, pop or whistle and the pipe failed.

Crofter Posted February 19, 2015 Author Share Posted February 19, 2015 I have changed the fuel filter and when doing this checked the lift pump out, boost diaphragm and pipework are all ok, so I am thinking that the timing belt may have jumped a tooth, are they prone to that?
