Hi all,
A few weeks ago I wrote about my 2000 TD5 having all it's injectors failing (had previously been piggy backed). Since then I've had the injectors replaced and have eventually got them re-coded at a "Land Rover specialist". However, the garage is telling me the engine if failing after three-quarters of a mile and they are unable to find the cause.

Anyone else had any experience of this???

Early TD5 engines suffered from problems with cracked cylinder heads or a leak where the fuel pressure regulator is bolted to the head. It's a common rail diesel engine, but rather than having a diesel rail external to the cylinder head, Land Rover designed it to run along channels cast into the head. If it's cracked or if the regulator hasn't sealed, you won't get fuel pressure and I imagine it'll look like the injectors are buggered. I'm not right up on TD5's mind. Were your injectors tested and if so, did they come back as being faulty or were they just replaced as a matter of cause?

What pos said or the injectors have not been installed with new, clean washers.

TD5's a notorious for throwing a wobbly if the seal is not 100% perfect.

Get them to run the fuel purge procedure on the vehicle, pedal to the deck, ignition on carry on and have them listen for bubbling gargling diesel lines. They may need to let it purge for as long as a minute.

Then get them to test drive it.

If it now runs and continues to run no bother get them to investigate where the air is getting in (Pos's information may hold the answer).

I know a friends TD5 needs to be purged fully every morning and also after being sat for any length of time throughout the day or it will run for a while and cut out he's just living with it just now until he gets round to fixing it.

Hi Tom

Thanks for the reply. The injectors were tested down south and reportedly all failed!

Thanks for that DM - will certainly suggest this. Am honestly at my wits end - been without my Defender for 4 weeks now!

It's very unlikely for all of them to fail. Did they tell you exactly what was wrong? Bad atomisation / spray pattern? Not opening and closing, seat leakage etc? They either saw you coming and made a fortune out of your back pocket or you have another underlying problem. Take Discomania's advice and check that the fuel system is correctly purged. The only thing that would result in five jiggered injectors is a very nasty contaminant in your fuel (which the filter should stop) a serious engine overheat (in which case it will have warped your cylinder head if it was hot enough to cook your injectors) or your ECU / wiring loom is playing up. Another possibility of course is that the fuel pump in the fuel tank is playing up, they're not the best bits of kit in the world - quite under-engineered in appearance!

That's all I can really think of!

The in tank pump also has a filter on it

hows it failing, spluttering or just cuts out, if it just cuts out i had similar on a merc and it was the crank sensor
