unlucky alf

I have been chasing a problem in regards to the car I saved from being scrapped whereas it was discovered that no2 injector is doing nothing, After going through everything it turns out that the ECU seems to be the culprit, Now the thing is finding one of the exact part number is proving a pain mainly due to the two letters on the end of it, I believe those two letters are in regards to the software the car was born with, Also the first block of four digits seem to denote the year, mine starts with 4x43 so the first digit makes it a 2004, Anyhow as I look more into it even if I get one of the exact part number it would have to be coded in unless I cloned it from my old one, but with the problems my ECU has this may not be possible, Either way it all starts to get a bit too expensive, So my thought was to buy a used complete setup, (instrument cluster+ ECU's etc) from maybe a later year car in which case apart from the injectors having to be coded in, mileage incorrect & wrong VIN number (all of which would be issues anyway) what other problems would I face?.

Just an update, , , , , ,I have now done an Ohm's check on the replacement injector & that checks out ok, I checked the others while I was at it & all good, But even more annoying that the old one I took out also checks as ok as well, So that'll end up going back in to save me a coding job.

Hi, I am having issues with one injector not working, I have changed it with a 2nd hand one & that hasn't resolved the issue as that seems not to be working either (no clacking sound), Have checked for voltage getting to it with the key in the on position expecting 12 volts but it's only showing 5.3 volts, I then checked all the others & they also read only 5.3 volts but those injectors are working fine, I wanted to check the circuit for the pulse signal but my 12v test lamp wont work at that low voltage. So a couple of questions really, firstly is this 5.3volt reading normal?, & secondly Assuming my problem is maybe a pulse issue is there a common cause for it?, , , , , Many thanks.

What is the situation in regards to injectors & numbers?, I see listings on ebay quoting long numbers that don't even appear on the item such as EJDR00101Z / 2S7Q-9K546-AH, Is that something i should be concerned about?.

After much searching on the net & looking for ideas I came across probably the most simple & obvious test, Just going along with a long screwdriver & listening to the clacking of the injectors, So this morning brandishing my magical long screwdriver i set about giving that a go, , , , , ,Bingo!, one injector not clacking, & just to double check i unplugged it & the engine note stayed the same, So hopefully that'll sort it when I can get hold of one, so what is the procedure on fitting another as I hear it has to be coded in or something & is there a club member that does this?.

My neighbours code reader turned out to be next to useless & would be more at home in a Xmas cracker!, In regards to a faulty injector I had actually read that somewhere but not how to find it, Would a leak off test show it up? (something I have never done), I have just stuck my nose into the turbo inlet this morning & although there is no side to side or in & out play it doesn't spin what I would call freely, would the ' drill hole & Mr Muscle' help with this?, , , , ,sorry with all the questions but playing with diesels is a pastures new for me, Oh & no engine light on by the way, , , , Many thanks for your help so far.

Hi John, i know my neighbour had some sort of code reader so will find out if he still has it, & in answer to your question, yes the diesel smell is pretty much all i do smell & the more you rev it the more smoke you get, & from cold it is a right pig to start almost like a petrol car when it's flooded it starts lumpy then smooths out a bit but with an uneven tickover, I did try the hanky thing & that stayed white so I'm hopeful that is one scare out of the way!, Anyhow time to grovel to the neighbour!,

Many thanks John, The guy i got the car from said that he had the sills replaced so i am hoping that worry is eliminated, Somebody did tell him that the smoke could be the turbo but as I cant smell oil in the smoke I figured that wasn't the issue, But saying that my knowledge of turbo's is very little. The coolant level is a bit difficult to monitor as the car isn't being used but a good sniff of the expansion bottle & a visual check shows no sign of contamination & no sign of custard on the oil filler cap either, I will try the hanky thing & see what colour that catches, (hopefully not a pinky colour!) but smelling it it has a strong smell of diesel, This is the first diesel engine I have had to attack as i have never had issues with one before so pretty much going in blind, As it is a right pig to start from cold I have ordered some glow plugs to see if that will at least help the starting problem, I will report back on any progress (if any) is made.

Hi all, New member & new Jag owner, I am one of those people who hates seeing cars going to scrap & would rather save them where possible, Anyhow I have just purchased a 2004 X type estate 2.0 diesel which is very tidy for the year & good service history as a replacement for my old Rover 75 which got beyond saving (I saved if from scrap 10 years ago & got 80,000 out of her), The Jag seemed the obvious choice as the look & size is very similar to my old Rover so when I saw one come up with no MOT that needed saving I jumped at it, I done my homework first on the bad starting, erratic tick over & smoke issue this one has & I thought I had it covered, (EGR problem was what I got from asking around). So I set about getting under the bonnet today & removed the EGR & manifold, & sure enough the EGR seemed to be stuck solid so replaced it, Started the old girl up &, , , , , , , , ,dammit still the same, So my obvious question is where do i go next?, The smoke has no oil smell to it so i guess that eliminates the turbo, The smoke looks kind of white in colour which to what i read is due to it running lean, I am sure others have got better knowledge than me so I am passing it over to you guys!, , , , , ,Many thanks.
