Is it leaking fuel with the ignition on? If not I had several instances where mine would fail to start and eventually after holding down the throttle it did fire up, Each time I had this fault I would strip the injector loom to find it covered in oil, a quick clean and it would be perfect for a while, I then purchased a new loom and sealed it correctly. This worked for a while but once again I had issues, upon inspection the loom and injectors were clean and oil free. The only options I had left were the FPR or injector rings and as I had a set of rings in my toolbox it made sense to look at them.
This is what I found:  Click image to enlarge Click image to enlarge I cleaned up the injectors with a copper brush and fitted new rings and washers, she has run beautiful since. The job is only a few hours slow time work. 90 wolf - Jasmin http://www.defender2.net/forum/topic39408.html 90 V8 - Maggie http://www.defender2.net/forum/topic42564.html 110 TD5 - Buggsy http://www.defender2.net/forum/topic59029.html 52HG25 lightweight https://www.defender2.net/forum/topic72342.html D3 Hse - Fiona Capri 2l S - Anna Think I might have a problem............ |

Can second the value in changing the injector seals and washers. I used genuine items and borrowed the correct puller to extract each one. Just take your time and have a good read of the workshop manual and it's easy enough

No. Right now there is no obvious fuel leakage - and no drips on the floor. I replaced the injector loom about 1 year ago due to oil in the red ECU plug and have checked it several times since and found very little oil. Thanks for the suggestion about the injector rings - so far I've not looked at them. I'll also try starting with the throttle at max to see if that makes any difference. |

Check the pipe that runs along side the head, it has metal ends but the centre section is rubber. Mine split and only leaked out with throttle on, you will have to take the engine cover off to see it. Ray

Thanks Ray - I can see the pipe. The front union looks like fun to get to  Would a split in that pipe prevent startup?
Is there any truth in the "300 rpm before injectors fire" comment in the other thread? I don't much like the look of the starter motor top bolt. I guess there's a knack to undoing it? Maybe I'll try some easy-start into the air intake. That'd boost the cranking... |

Yay - it's started!
 But very reluctantly - and not because I've done anything since starting this thread. However, its lumpy and sounds like its running on <5 cylinders. Despite still having no error codes the Nanocom seems to confirm this - see photo below - which suggests that 4 & 5 are odd compared to 1/2/3. What could cause this? 4+5 injectors not firing - maybe loom failure? Head gasket? The latter would seem unlikely as it has no other HG failure symptoms

Well...
I've stripped and cleaned the injector loom (no improvement), checked the red ECU plug for oil (none found), checked inside the ECU for oil (none found), spoken to local indy, located the Crank Position Sensor for removal & cleaning (no improvement). As yet I've not tried removing the injectors to replace the washers & seals - for such an expensive part I'm not sure about using the pry bar / water pump pliers / allen key extraction methods. The sump oil hasn't risen and doesn't smell of diesel so I expect that the injector O-rings are OK. However, tonight it fired up (reluctantly) and ran lumpily for about 30 mins until I switched it off. The video link shows it tonight: https://youtu.be/uQfEPjD5Ubo Does anyone have any further thoughts? The local indy has offered to visit with his proper LR diagnostic kit, so I'll probably get that done first before towing it to his (already overflowing) car park. Thanks - John |

My o-rings were fine it was the copper washers that failed. All I used was a slide hammer on the correct area to attach the special Land Rover one, I could only get one leg on but they all came out fine with no damage. 90 wolf - Jasmin http://www.defender2.net/forum/topic39408.html

Progress report: the in-tank fuel pump is delivering <1.5 bar of pressure. It should be 4 bar at the FPR temperature sensor port. All filters are OK so it's time for a new WFX000260 pump/sender assembly from VDO.

Pump is the same as a discovery 2..... just the float arm is different... takes about 30 seconds to unclip it and fit it onto the new pump.
Disco 2 pumps are generally cheaper than defender.... edit: and I just googled them and the price seems to have come down a lot for pattern parts... and from John craddock (as a quick example) the 110 pump was about £20 cheaper than disco!  |

Absolutely right. Garage just reported lots of black gunk which is being flushed out right now. They recommended the use of BP Ultimate or equivalent premium diesel because apparently they include anti-fungal anti-algae ingredients. |

A "Made in China" version of the WFX000260 is available for £49. I'm going for the VDO version which is 4x more expensive but will hopefully last >4x longer. |
