So does the oil problem make it run on 3 cylinders then run normal ????

Bearing in mind that ECU's are just computers, you know how computers can get if they don't get clear messages !!!!!
The oil contiminates the contacts and then can create a variety of poor running issues.
Your best bet is to have a look at the ECU end plugs and see if there is any oil.
Follow the link I put in a previous post and you'll do it easily.

Hi Muddy, just a piece of info I've come across today.
Assuming the injector loom oil problem IS caused by oil getting past the original 'O' rings on the harness plug, it is possible to buy them on their own.
The part number is accessed via this link and the good news is that they only cost coppers

I don't think that o-ring will help you. It only seals around the outside of the plug.
The oil that reaches the ECU socket is penetrating INSIDE the insulation of the individual wires and travelling by capillary action among the thin copper strands all the way to the UCU, and that can be uphill most of the way as in a Disco..
Regular plug cleaning will keep it going but the cure is a new oil-proof harness.

Hi Charles, my understanding is that the oil starts it's journey in the rocker space, passes past the male plug 'o' ring seals, into the female socket of the second loom and thence down to the ECU, so improving the seal between the male plug and the head, will actually reduce the problem.
That may be the theory and it would be nice to think so.
But if he has oil at the plug and socket no harm can arise by cleaning it out well.
Airline job .... after a wee spray with WD40 or similar.

Im thinking its more fuel prob than loom it did have some oil but i cleaned it and made no difference im thinking air in the sytem or **** fuel filter im just hoping it was deffinately a TD5 filter they gave me plus mine has the electric plug on it

I'm not special I'm limited edition
I haven't got a water trap on my TD5 and it starts fine. I'd try another filter first. At less than a tenner for a decent one it'd be worth it. The cheap filters often do play up.

On my old filter was a plug with electronic plug but it would'nt screw into my new one so i have plug just dangling their my filter was about £8

Could it be the heater plugs?????

No it won't be the glow plugs. They are only required to start the vehicle in cold weather.
It also isn't the water sensor that you've left dangling.
I think it's more likey that it's air being drawn in from something that you may have disturbed while changing the fuel pump. The pipes above the pump are prone to chaffing and rubbing through. It only takes the slightest leak to suck air in.

No it does'nt screw in its a smaller hole

could it be the wrong filter?
and therefore the wrong size, and therefore sucking in air..?
what's the part number on the filter???

there is'nt a part number on it and ive thrown the box

the drain plug on the bottom of the filter can crack if screwed in to tightly.. this will suck in air.
if it is not tight enough... it will suck in air.
if the 'water in fuel' sensor out of your previous filter does not fit, it suggests that you have a 200/300 filter on there... which has the smaller hole for a simple drain plug...

so ifi have a 200 or 300 tdi filter would it cause me problems?
There are more than one fuel filter setups for Disco TD5s.
Mine is May 2004 and does not have a "water in fuel" sensor. But it does have a plastic drain plug doo-dah that fits in the bottom of the filters.
I save the poly bag the filter comes in, and after fitting the filter I slide the poly bag up over the filter and then slip a rubber band (usually a couple) up over the bag to keep it on.The rubber bands can circle the poly bag above the rubber o-ring joint, so that gets protected from the worst of the road muck too.
Then I snip a tiny bit off the bottom corner of the bag in case any water gets in - it can drain out.
At filter change time just rip off the poly bag and unscrew a lovely clean filter, from a clean joint at the filter housing.
