TD5 Air In Fuel System, Cutting out

leaky regulator/O ring, chaffed fuel line on the chassis rail, faulty injector seal/injector, cracked filter housing, filter drain plug/water trap stripped thread/loose. etc etc. All are common faults.

Could it be a crack in the head. Ive heard that they go under the injector seat so combustion pressure will enter the fuel gallery. I know you said you have had a new head but it may be worth compression testing the 4 cylinders you can through the glow plug hole.

If you think it's air in the fuel line stick a section of clear tubing between filter and pump to confirm

Cheers gR@HaM, I had just tried that last night. I made up some fuel connections and lines, by-passing the cylinder head and directed them into a large 5 liter glass jug, it is pumping fuel really well, but with fine bubles that never seem to clear even after full purging cycle. So that means it's in the line direct from the high pressure pump side. I then done the same on the low pressure return to the pump at the tank, which is meant to feed the high pressure pump, there's no air in that, so the pump must be creating air in the high pressure side to the head. Which is strange even with the tank filled to the neck, but then it is a Land Rover. I removed the pump again for second time, took it apart checked it, everything seems ok. I'll try the pump in once more with every thing cleaned and checked, then after that is a new pump. That'll be the second new pump in two years, but i suppose the wife almost running it out of fuel every other week doesn't help.
Cheers.

I put a new fuel pump in, bled the system and it started up and ran well, but again cut out at the bottom of the drive as if out of fuel. When you purge/bleed the system it allways goes the full cycle and never cuts out as if primed. Can any one tell me what actually signals that the fuel is primed in the head and up to pressure and then cuts out the fuel pump. Has any one ever had a new fuel pressure regulator that was faulty also.
Cheers Mike

Just to finish the story. I bought a new pump, fitted it, the TD5 started perfect then sat ticking over for a while, I took it up the road and it went perfect. I brought it home stopped it and went out in it again about an hour later and it stopped up the road as if running out of fuel. A secondhand ECU was fitted and it done the same thing. To cut another long story short, after another few weeks of trying every single thing possible it worked out to be a couple of wires rubbing through the loom down the back of the engine, these lovely little bitches would intermitantly short out various parts of the electronics and shut them down, then show no signs of their crime on the diagnostics..... Ba*****s

There is a so called "air bleed valve" within he fuel filter housing nr.7, unfortunatelly i dunno the part number maybe someone around here will help....replace this one before u do anything else

I had one recently that had a new head-one of the injectors was loose-same problem, get it checked, not a big job, also make sure genuine injector washers were used.

I have the absalutely the same problem could you tell me what was the problem if solved? thanks in advance

i had a problem simler to yours first with out pulling things apart think how the diesel system works compression will get into the headand come out down the return back to the filter now the return goes back to the filter air will be in the filter . the diesel pump in the tank will return that air lock. i took off the return coming from engine to the filter and the union from other side of filter blanked off the filter housing joined the two pipes up so now the fuel will go straight back to the tank so the pump will not suck eny air up from the pump side. that will prove you have air coming from the head
because my filter was hot and making a bad niose
and thats how i knew

Hi Folks - can you tell me where I can locate the wires at the back of the engine that were shorting out? I've just replaced injector seals and loom due to the cutting out problem and the car started, ticked over, drove home, now it won't start! any other suggestions?

I have had this very problem for the past few months. It will idle all day but as soon as I drive it or rev it 2000rpm or more, within 8 minutes it cuts out.
Can you tell me where these wires are so I can check.

Looks like the O/P was another classic "Use 'em and lose 'em" new member who joins the forum, asks a question, gets an answer then clears off never to return.

Just had a read at this quite interesting.
Lightning did you notice that the OP started this in 2010.....

Did anyone manage to make any progress on this?
I'm having a total shocker. Car was OK, but cutting out when pushed, and with lots of diesel in the sump oil.
So we changed the injector seals, and now the thin will only run for 30 seconds before running out of diesel.

Any ideas?

Only the seals? whatb about the copper washers?

With the wire chaffing round the back of the engine, I can only see the one that looks like it goes into the wastegate is that the one we are talking about? I'm having the same issue, gave that wire wiggle and it appeared to run fine once I started to rev the engine the it started to struggle again.

Had exactly the same and took Zoners' advice and changed the injector seals - cured.
