Speedy_Gonzales Posted February 17, 2008 Share Posted February 17, 2008 2000 TD5 Defender, ran perfectly previously but: Started yesterday, in 4th and 5th (though most noticable in 5th between 60 & 70 mph) gear there seems to be a slight misfire which seemed initially like fuel starvation. Took her for a good run out to the Peak District today and she seems quite sluggish going uphill and on the motorway, at times struggling to hit 70 when in the past cruising at 70 was fine. Ive had a good look through the forums but it appears it could be all manner of things from injector harness to ECU.. Any ideas where I should start? Am I best getting the fault codes read first or using a process of elimination to discover the issue? RE: Fault Codes - are there any cheaper alternatives to Nanocom or Rovercom?

Does anyone local to Cheshire have a Nanocom that they would be preapred to plug into my TD5, happy to travel to you! Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 18, 2008 Share Posted February 18, 2008 From the misfire I would guess the injector harness, it would be where I would start anyway. Quote Link to comment Share on other sites More sharing options...
SteveG Posted February 18, 2008 Share Posted February 18, 2008 From the misfire I would guess the injector harness, it would be where I would start anyway. just so you are aware - Chris, GBMUD, had similar problems when his fuel pump started to go. Has your fuel pump been lowder than normal recently? Thanks Steve Quote Link to comment Share on other sites More sharing options...
MINESAPINT Posted February 18, 2008 Share Posted February 18, 2008 I had something very similar with my Td5 a couple of years ago. It turned out to be the Turbo activator not activating due to corrosion. A £25 squirt of WD40 did the trick. I now oil the shaft periodically and have had no further problems.

Speedy_Gonzales Posted February 18, 2008 Author Share Posted February 18, 2008 Reply to All, This is why I asked the question of whether it would be preferential to run Nanocom or similar on it first... It could be any or all of the above reasons!!!! Potentials list to date: * Injector Harness * Injectors * Turbo Activator * Fuel Pump Hmmm......

It could be any or all of the above reasons!!!! Potentials list to date: * Injector Harness * Injectors * Turbo Activator * Fuel Pump Hmmm...... No offence but i think everyone is answering, its just not the direct answer that you are looking for. Firstly ... Lift the bonnet ... get in .. check for signs of the above. If after a few hours it leads to nothing then run Nanocom. Or run Nanocom .. see if it shows anything .. It wont tell ya if your fuel pump has been starting to get noisey recently though. Neither will it pull ya a can of WD40 for the Turbo activator. Probably wont even differentiate between an injector fault or a harness fault... Need eyeballs and maybe a meter for that Quote Link to comment Share on other sites More sharing options...

If id have gone down that route, I would probably have rebuilt the engine by now!!! I will start with the suggestions made (thankyou to you all for your advice) and see where it gets me prior to checking out fault codes with nanocom etc..

BogMonster Posted February 18, 2008 Share Posted February 18, 2008 Some of the faults (fuel pump and injector harness) will not show up as fault codes on any diagnostic computer 80% of the time, so you won't necessarily be any the wiser and it doesn't pay to rule out those things "just because the computer says it is ok". I have long since lost count of the number of Td5s I have seen in the workshop where the engine is running like a bucket of sh** and the computer says there is nothing wrong with it!

"Computer says Noooooo"!!! No worries, I guess I should check other issues first and follow the elimination process...

JST Posted February 18, 2008 Share Posted February 18, 2008 is it at high revs in all gears or just 4th and 5th at 60-70? Quote Link to comment Share on other sites More sharing options...
Speedy_Gonzales Posted February 18, 2008 Author Share Posted February 18, 2008 is it at high revs in all gears or just 4th and 5th at 60-70? Used it again today and it was just doing it in 5th.... Somewhere [roughly] between 60 and 70 (never the same speed though).... It is still intermittent though, sometimes it doesnt do it, sometimes it does, sometimes it will allow me to put my foot down and get up to 80, other times it struggles getting past 65-70... Any ideas?? Thanks Quote Link to comment Share on other sites More sharing options...

MINESAPINT Posted February 19, 2008 Share Posted February 19, 2008 My money is on the turbo activator. Just find it, give it a squirt of WD40 and waggle it about a bit. Lubricate monthly in the future. Hey presto! MINESAPINT Quote Link to comment Share on other sites More sharing options...

Lubricate monthly in the future. Hey presto! MINESAPINT Well it looks like good news! Just had a play with the turbo activator and cleaned up the movement, took it for a spin and problem seems to have gone <fingers crossed!> Many thanks to Minesapint, and if we meet up some time, yours is certainly a pint! Thanks for all the feedback, big up to the LR4x4 massif! Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted February 19, 2008 Share Posted February 19, 2008 Just goes to show that people can suggest causes and potentially diagnose problems but in the end it's initially down to a hands on investigation, observation and elimination.

Glad you got it sorted I agree, though the info from minesapint was invaluable, having experienced it himself before he knew the symtoms (Sp?)... I knew it could have been half a dozen things having performed a search and read loads of other forum posts before posting myself... Quote Link to comment Share on other sites More sharing options...
NicTheOrange90 Posted February 20, 2008 Share Posted February 20, 2008 Is the Turbo Activator the rod that is on top of the turbo? Is it supposed to be 'fixed' without the engine running or should you be able to manipulate it in and out? Did a search in the LR Workshop manwel and could not find the named item...

Did a search in the LR Workshop manwel and could not find the named item... I quote minesapint: "With ref to where it is located. It is on the top of the engine a bit hidden on the nearside of the vehicle. Look for a small zinc plated cylinder about 2 inches diameter and 2 inches long with a 3/4mm shaft protruding from it. When the engine reaches the appropriate engine revs the shaft should move to engage the turbo. I believe your problem is that this shaft is seized. You will need to lubricate it and work it in and out. This is possible using a screwdriver and part of the engine as a lever." It sits right on top of top of the turbo, with a rod that protrudes from inside it and goes under the heat shield to a mechanism. Spray WD40 all over the rod and where it locates into activator, then apply pressure to the nut half way down the rod (it meets a plastic tensioner on my mine) in the direction of the bulkhead, it should move with a bit of force... Hope this helps. Quote Link to comment Share on other sites More sharing options...

NicTheOrange90 Posted February 20, 2008 Share Posted February 20, 2008 I sprayed it today but was not sure about the amount of force required. Took it for a test drive and seems like its already up on power, so will play a bit more at the weekend. Quote Link to comment Share on other sites More sharing options...
MINESAPINT Posted February 20, 2008 Share Posted February 20, 2008 You need quite a lot of force to move it initially obviously depending whether it is seized. I note lubricating this part is not in the service schedule. MINESAPINT Quote Link to comment Share on other sites More sharing options...

MINESAPINT The activator rod appears to be alloy also, which is probably why it sticks, I imagine that surface oxidisation and dirt clunks things up, strange that its not a service item given this design!
