Fuel issues with TD5

Hi all

I have a TD5 with 115,000km on the clock.It started running roughly, losing power and blowing black smoke. If I drain the water sensor on the bottom of the fuel filter it seems to come good for a while... so I put it down to a bad batch of diesel - possibly with water in it (although the water sensor light was not coming on).

It seemed to be getting progressively worse, occuring more often, so I replaced the fuel filter, and put some diesel injector additive into the fuel.

It was OK for a couple of days, and then stopped. Drained the fuel filter again, and it ran for a bit longer, then the next time it stopped, it did not come good when the water sensor was removed.

I then removed the fuel filter, drained and replaced - it seemed to run OK again, so I figured it must be contaminated fuel.

I removed the fuel pump, fuel tank, and even the filter mounting assembly and drained and cleaned everything thoroughly, including lines. Once it was put back together, with new fuel, it ran OK for a while (half an hour), but has started running badly again.

The only thing I haven't checked are the injectors and the pressure assembly bolted at the back of the cylinder head, however I doubt if the problem is tup the front, as I can't see the association as to why it would run well when the fuel filter is drained?

I am totally bewildered... any suggestions?

I just drained the fuel filter again, and it was running fine.... on a test drive it lost power a few times. I stopped the engine, restarted and it was fine. At one stange I was going alone a freeway and it lost power.... I turned the engine off and on again as I coasted... it was fine.

This is sounding more and more like an electrical problem... possibly ECU? or the fuel pressure sensor malfunctioning?

I HATE BRITISH CARS......... can't wait to sell this PIG and buy a new Mazda CX7. At least the Japanese know about quality control.

Checked the injector loom for oil contamination? Sounds like it's made its way into your ECU.

Pull the big red plug off the ECU and see if there's oil in it - if there is, wash it out with brake cleaner and blow out with shop air. If it's in the computer, you can kiss a few thousand dollars goodbye.

The other possibility is an air leak somewhere in the system. Air sucked into the fuel lines will cause these sorts of symptoms. Bleeding the filter will cure it for a little while.

Just a thought, but have you checked that the fuel tank breather is not blocked? This can give symptoms like the ones you are describing. The next time it stops just remove and replace the fuel filler cap and see if that makes a difference.

That remark isn't going to endear you to a dedicated Land Rover forum, is it? I see you have already had some helpful replies, which shows what a tolerant and good-hearted lot we are. :-)

You can f*ck off right now (on foot seeing as you've broken your Landrover).

Can we aasume that for the 115k km it was fault free and looked after, or abused and bashed. You get in return what you put in.

So insult someone else and good luck with the jap crap, most people here have varying vehicles of different vintage that are cherished. You clearly are'nt going to be cherised

Thanks to everyone for their help... and to those I offended... sorry. I did write that posting suffering sever frustration and dissapointment after spending 4 hours in 40 degree heat laying under the TD5 to no avail.

The goods news is I fixed it. I (suspect) I had two issues. One was because I had removed and cleaned all of the fuel lines from the fuel filter mounting to the fuel pump, that it had an air lock. I also believe there was a dirty contact issue with ECU main plug.

On another note.... whilst delving under the bonnet looking for problems I discovered and resolved two other long standing issues. The first was the smell of coolant that I could not locate. As it turns out the steel pipe that runs along the exhaust manifold side of the head had a build up of corrosion at the firewall end, that was causing a leak. This in turn was spraying down the block and onto the bell housing. The second issue was a juddering clutch (I posted a question about this several months ago). Obviously the coolant was making its way onto the clutch plate/fly wheel.

Anyway..... at least it's fixed. And once again sorry to those I offended.

An apology, on usenet? Wonders will never cease ;-)

Glad it's all fixed, they're good vehicles on the whole, and the hype about japanese etc vehicles never breaking down or needing work is somewhat overblown, otherwise there wouldn't be so many garages for them! If you join an owner's club for any vehicle, you quickly get a list of common faults for any car.

Thats why our Nissan Terrano has eaten 2 gearbox's, a clutch and a clevis pin in 2 years and 40,000 miles!!

At least a LR will normally take you to beyond 100,000 before it requires attention!!

I know we probably have a bad Nissan, bnut you may have a bad TD5 also. Once you get this problem ironed out, stick with it.

Have you listened to the fuel pump? Is it noiser than it used to be - they are known to fail and provide reduced fuel pressure to the engine.

That seems to be only slightly above average for Terrano's.
