1982hotdog Posted January 28, 2009 Share Posted January 28, 2009 hi i have a 200 tdi disco j reg i was driving down the road as normal and my car cut out. we got fuel at the lift pump and then out of the filter but not out of the pump so then got towed home so then we changed the pump then got fuel at the injectors but still not running right so think the cam belt may have moved i have been trying to fix it all weekend i done the timing and new fuel filter it will now tick over just but wont rev up some times if you hold it flat out for a long time it will rev up but some times it wont i thort it might be the lift pump but i had it running then removed the bleed bolt in the filter housing and it p==ed out so its not the lift pump today i removed one of the injectors and then put the pipe back on and turned the key and it sprayed good then tryed one more that was ok dont know what to do now i think i might have to start again with the timing Quote Link to comment Share on other sites More sharing options...
rocky Posted January 29, 2009 Share Posted January 29, 2009 Hello mate, it still might be the lift pump. I was helping a mate this week with the same problem on his mitsosh***y, plenty of fuel at the filter but not enough to keep it running under power.

Orange Posted January 29, 2009 Share Posted January 29, 2009 Same experience with a friend at a P&P day in December. Engine would run and drive the vehicle on tickover, but as soon as any load was applied to the engine it would die... Changed the lift pump and it was much better. It was at that stage that we discovered he had a punctured fuel pipe on top of the chassis. Never noticed it before due the the lift pump not being good enough!!

1982hotdog Posted January 30, 2009 Author Share Posted January 30, 2009 thanks for your help i wll try a lift pump and i dont think its the pipes because ive got a short pipe from the lift pump to a tub of fuel Quote Link to comment Share on other sites More sharing options...

BogMonster Posted January 30, 2009 Share Posted January 30, 2009 Looks a bit dodgy as in when you put it on a test rig the spray pattern is carp, or what? Quote Link to comment Share on other sites More sharing options...
landkeeper Posted January 30, 2009 Share Posted January 30, 2009 you can rig up a fuel feed direct to the injector pump with a squeezy bottle full of diesel just make sure it's higher than the pump , soon tell you if the engine is reving right if it does it's the lift pump more than certainly Quote Link to comment Share on other sites More sharing options...

1982hotdog Posted February 1, 2009 Author Share Posted February 1, 2009 well today ive been out side in the snow all day and redone the timing it now starts and runs but when i try to drive it its very slow it will only do about 40 mph and it hard to pull away i think it might be the turbo now o and theres a litle bit of air in the fuel (i have clear pipes)not much is this right or is there not ment to be any as i dont know because normly you carnt see Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 1, 2009 Share Posted February 1, 2009 There should be no air at all in the fuel so if you have air that is probably the cause of your problems. Check for obvious air leaks (loose connections around filter etc) if you don't find any then take the carpet up in the boot, take the hatch out in the middle of the boot floor and check the pickup where it goes into the top of the tank. I saw a 200Tdi with similar symptoms to yours once where the steel pickup pipe had corroded right through just outside the tank and there was a pinhole air leak on the suction side, no fuel leak due to it being suction rather than return but it buggered the performance up completely. You might be able to braze it but if it looks anything like the one I saw you will want a new pickup! Quote Link to comment Share on other sites More sharing options...
1982hotdog Posted February 1, 2009 Author Share Posted February 1, 2009 my tank is a 25l tub in the boot i carnt see any problems but there air coming from some where its not much very tiny bits when its running the fuel pipe makes a tapping noise and moves and if you hold the rubber joints you can feal it pulsing is that right and i dont think i can hear the turbo spolling up i opened the air box it was full of leaves so i cleaned it and took out the filter then tried that but its the same oh year my car is a range rover i only asked if the disco bit because its got a 200tdi in it thort it would be easyer that way Quote Link to comment Share on other sites More sharing options...
