Hi all Had my Sdi's in for 2 years but the nozzles are worn as they smoke more than ever and its taking longer to start and using loads of fuel, there's some 200 tdi nozzles on ebay for £70 ish (non descript) should I wack a set of these onto my sdi bodies and see how they go?

You would think that, when i was playing with sdi hybrids they leaked less than two months from new. it wouldn't stop the car from starting just make it difficult to start.
problem with checking them visually is diesel is heaver/larger than air, a pipe might be diesel tight, but not air tight. A problem compounded by the leak off being braided, so visual checks are useless unless they are that far gone as to let derv juice out.
If you've opened the fuel lines i imagine it wouldnt help starting when the engine is trying to purge the air from the system.
I have a length of non braded leak off pipe so will try that its just sooo cold to be messing about with it was out there 6 hours today, if there is a leak it must be post pump as everything was ok until I disturbed it
Yeh as I mentioned two of the new nozzles appear to be blocked or faulty I'm wondering if this is the case I may have stuffed my pump up?
another set of 200bar injectors in and still no joy it is for sure looking like a duff pump! iv'e just been out to it there is fuel reaching the injectors it will only start for a short period using aerosol but while running there is no throttle response at all and then it dies off, the injector 1 wire is tip top as are all the leak off/return pipes

Shove in a known good set of injectors first - you only need to borrow some to try to pinpoint the fault 
I'm looking at a couple of injector pumps on ebay am I right in thinking these are plug and play just need the obvious timing up or is this easier said than done?
I've only ever changed common rail pumps which are a much simpler affair

Yes mate straight swap, just make sure the one your buying is locked or timed up, if the pulley has been off and been knocked out of time, its a right faff to get it back spot on..
But yeah, sling it on, time it up and it will go!
trouble is tho the ones i'm looking at (cheaper ones) have had the pulley off so the timing will have been disturbed
my faults are, fuel to the injectors but doesn't seem to be under that much pressure or enough to crack them open, plumes of white nasty smoke so maybe fuel is getting in there but not at the correct time, thing is I only swapped the jectors and its all gone Pete Tong!

Sounds like the timing is retarded..
If theres white smoke, its injector fuel but obviously at the wrong time..
If you do think its an injector, you could be mentle, take one out, fit it back to the fuel line and get someone to turn the car over, see if it opens, fuel will be everywhere mind..
Id re-check the fuel pump timing mate..

yeh will do what you said sounds like a plan I will just put an old coffee jar over the end, (good thinking there), anything to pin point the prob and save money of course, just cant see why the pump timing would be out when I ain't been nowhere near it but as I said before in this thread if there were restrictions in the new nozzles (blocked or just faulty) this may have perhaps thrown the pump out in maybe more ways than one, or even just pure coincidence that my pump timing has failed at a similar time, are the pump shafts not marked up or is there a right/wrong way for the pulley to sit surely its not just a guessing game for the pump timing?
Sorry hadnt read the full thread..
Have now..
So will it start now or not?
I reckon timing solenoid or metering solenoid in the pump tbh..
If you've got new nozzles and it ran for a bit with new injectors id say something in the pump has gave up now..
Try that injector test though, see if they are firing..
Id say the timing solenoid is knackered and retarted the timing.. Could be the metering solenoid also though..

well Chaz it began to loose power the more I put my foot down the more it slowed it was fine on tick over so had to drive home on tick over came home and swapped to a different set of jectors now nothing at all
Have you changed the fuel filter?
My ZR did this..
Was going down the motorway, would get to 70 and it would splutter and mess about, but it would sit at 65 no problem..
I was thinking it was a sensor of some kind, as it only happened in 5th over 70..
Turned out the fuel filter was full of water..
Obviously when it demanded more fuel on load it couldnt supply it :lol:
If you have tried that..
Run a new pipe from the pump, straight into a clean jar of diesel, see if it goes..
It sounds like fuel starvation to me.. Possibly an air leak in the fuel lines also?

to be honest I aint touched anything pre pump so I will get a new filter in there before I go down the road of replacing the pump, Dan said last week that it sounded like starvation infact on reflection using the priming bulb disturbes all the crap in the system maybe this is the case, cross your fingers for me guy's wont be able to look at it until Sun evening now though .... Update Just purchased a new filter from a bloke down the road from me gonna give it a go
new filter in primed it for 10min or so and nothing I'm loosing patience with it and frozen stiff
Did you prime it with the bleed nut on top open and wait until fuel seems out over the filter? If so, I think either your priming bulb is duff, or you have a blockage between the bulb and the pump, or an air leak between the tank and priming bulb.
Can you blow down the fuel feed from the fuel tank, this might dislodge any blockage temporarily? If not, you might need to try some compressed air, hope you can get to some.
right, I took the fuel lines off blowed down them and there was some resistance from the main tank to filter feed anyway whatever was causing this resistance/blockage has gone and put bulb and filter back on and now the bulb primes up much better and gets solid as it should but the bloody car still wont fire up
