Hi Guys - I wonder if you can help me at all please?
I have a 2002 L322 TD6 which I have owned since last august. (90k)
It has always been lazy starting. I had it looked at and found it had a lower powered battery than it should (probably due to the difficulty of shoehorning the right one in the space) and when I changed that it was OK for a while.
It has got worse recently and now wont start at all. Various garages have looked and not been able to find the fault of the lazt starting using diagnostics. Does this sound like anything you have come across before?
I would appreciate any advice befoer I take the plunge and go to main dealer as I reckon that they will recommend the usual injector changes and associated work which will doubtless cost me about £2k.
If you have any advice for a relatively naive Range Rover owner, I would be eternally grateful.....
Kind regards
Edward Harrison
 
I assume its turning over .(All be it very slowly).....it sounds like its fuel related to me possibly the fuel running back to the tank AFTER you've switched off ....Have you tried fitting a Non-Return valve in the fuel supply to the injector pump ????

If its like the P38 (I'm not familiar with the L322 setup) the fuel pump only "Pumps" when the engine is Cranking .....(To Start) then IF the fuel IS runnin back to to tank you'll be pumpin yer fuel from 6 feet behind you just to start her up !!!
 
Hi, Its turning over fast. When I say 'lazy' I mean it takes a while to start - maybe 3 secs or more. It sounds fine now, it just wont start. I have turned the key off and on a few times and the glow plug light is on fine. Fitting fuel line non return valves is beyond my limited skills really, but I would have a go as I seem to be able to do most electrical and mechanical things with the right amount of internet research! Do you think I should try anything or go to a dealer. Alternatively, I would like to find a specialist in these parts - Lymington, between Bournemouth and Southampton, on the south coast. Any ideas?
Thanks for your help ........
Edward
 
check you are getting power to the glowplugs by putting a voltmeter from one glowplug to the engine block. You should get 12volt or thereabouts. If you have 12 volts, next step is take out a glowplug, connect it across the battery and see if it gets bloody hot! If it doesn't get hot, replace the glowplugs.
If you don't get 12 volts at the glowplugs, check the glowplug relay.

Thanks Data, Can you point me to the location of the glow plugs please?

Not on a TDV6 I can't, never seen the engine but they should be obvious when you get the covers off, there will be a biggish cable and a metal link across the top of the glowplugs, as it's a V6, 3 glowplugs per side:D
Otherwise download RAVE which I assume will show the engine as it covers the L322:D
 
just a little something to add, its a straight six not the tdv6 thats in the discos. the glow plugs are under the inlet manifold, like he ^ says check all the glow plugs first but the biggest problem is the inline fuel pump packs up (under the car on the passenger side underneith a cover). get some one to turn the ignition on while you lay underneith , you should hear it prime for a few seconds then stop.
 
I had a problem with my old TD6 04 Reg
i came home one night and it wouldnt start the next day
took it to my local mec and they found out it had dropped 3 injectors and one of the fuel pumps where failing also
cost me £1200 to get it fixed
hope you aint got the same problem
 
Hi Guys,
Thanks for your help. I found the glow plugs. (You are right, it is not a V6, I am not sure why the tag says I have a V6, but I will change it.)
However, I cant find any power at the glow plugs at all. I have now changed the glow plug relay, but still no power at the glow plugs. Really getting concerned now and that £100 an hour main dealer visit is starting to look a possibility. Any other advice would be very much appreciated. It does appear that we have fuel getting there, but no glow plugs. I have checked pretty much every fuse.
 
Hi Mate Look on this site
The Green Oval - Downloads | Land Rover Data

you'll get the Rave off there. just a quick follow up to you problem.
im no expert on these by no means but i did have a shed load of problems with my td6
when mine stopped running and my fuel pump and Injectors went i was getting fuel though also, the garage told me there are 3 fule pumps on the td6 and all 3 need to pump to get the required presure to the engine?
good luck mate hope this helps
 
Download RAVE, then double check that it's the glowplug relay that you have replaced, then check where the relay gets it's live feed from. As a test, you could use your jump leads from the battery positive direct to the glowplugs and see if it starts.
 
Hi All,
I have not got the RAVE yet, but I will later. I have been told that the glow plugs are pretty immaterial in modern engines and would only be critical in very cold weather. Not sure of the truth of that. However, I have had the injectors 'tested'. They block the common rail apparently and have found fuel leaking back up through two injectors. The slow starting may have been due to one injector being out for a long time and now a second has gone, the engine wont start. Does this sound logical? They are pretty convinced its not a fuel pumping problem. Bosch injectors are £185 each and easy to replace so I am going to have a go. Any ideas (apart from getting RAVE). Thanks in advance ............
 
Hi, I have a 2004 Range Rover TD6. The battery was drained, so I tried to charge it, but it didn't work, so I bought a new battery. I installed the battery today and the car started right away. I quickly turned off the car and disconnected the battery as one of bolts had fallen down in the battery compartment and I couldn't get it without removing the battery. After that I connected the battery again and didn't start the car. One of my windows has not worked for a while, so I though I would go through the fuse box to see if that was the issue. I pulled out a fuse which resulted in the alarm going off. I put it back in which made the alarm stop. I found the broken window fuse, but didn't have a new one to replace it with.
I then wanted to start the car to take it for a spin. I turned the ignition and all the lights when on as normal and the engine turned, but would not fire. And idea what is wrong?

This at last sounds like someone has thought about it that understands the system.Excessive leakback in common rail injectors is a big problem,there are several ways to check for it.The most basic which AA/RAC peeps do on the roadside is to give a quick sniff of easy start,as they will run,if only they could start.Other ways involve attaching tubes to the top of each leak off and running the low side pump,or pumps in your case with a TD6.
You can forget the glow plugs and fitting non return valves,neither will help your situation.
The injectors can be very difficult to remove on them due to carbon build up around the lower end of the injector - I have a slide hammer attachment to help get them out.

Sounds like you have triggered the engine immobiliser, on a P38 it would be loss of sync. There are set proceedures for disconnecting the battery. Failure to follow the instructions in the owners manual can cause all sorts of problems. It may have to be plugged into diagnostics to sort the problem, I'm not too familier with the L322 so not sure.
 
I think you are right. I have disconnected the battery a couple of times but the car still won't start. I am just surprised that the engine turns if the immobiliser is activated.
 
I think that is exactly what has happened. Any suggestions to how I can fix the issue? Do I need to take it to a RR service centre?
