Will these Injectors fit my 1995 XJS AJ16 Engine?
#21
Cheers! but slightly confused (I know!)
Can I mix: 3 X DBC 10423 with 3 X EBC 4430 (are these all the same) as EBC 4430 wasn't specifically mentioned in your very helpful reply
Assuming this works GF is going to be in 'Smug Mode' for quite some time!

I'm actually very surprised that the coils would burn out, that isn't common. I would expect that a set of 6 off ebay or a breaker like EuroJag from an X300 would work fine.

Alex,
I have no 100% idea what the Part Number change is in this particular case,
BUT
After 55 years in the Automotive Spare Parts Industry, I DO KNOW that numbers change for the slightest of reasons, as Warren already indicated.
Supplier is #1
Colour of the item is next
Upgrade, and backward compatible is another.
Rationalisation of supplier parts inventory is high up there, as in "one number will fit multiple vehicles.
If a part number is changed, and a supplementary "whatever" is required for that part to work, teh Inventory ALWAYS includes that in the verbal description.
Bad example whilst still on coffee#1.
Mitsi Pajero shocker will fit Triton, IF bolt #....... is used on the lower bracket. That bolt may be longer of shorter, but that is now getting way to complicated for this post.
I see NO reason why either will not work. At a dealer for example, under warranty, a car has a faulty injector, so ONE is fitted as supplied by the Parts Dept, and unless there are other components needed to make that fitment work, the mechanic simply gets ONE injector.
Whilst she is a Smug mode, get 6, and be done with it.

Hi Grant
Cheers! and while I haven't got your kind of knowledge and while I could be wrong, I can't see they'd be much difference if any between the Injectors for an AJ6 and an AJ16
Maybe on the Engine Management side but not on the actual 'Hardware' so when the GF comes up with the 'Goods' I am going to roll the dice and see what happens
Also Grant@Jagboi
I took out all the 'Basket Filters' from the Old Injectors and gave the Injectors a good hammering with a FBH! and got 5 out of 6 of them Spraying!
Although the 6th one doesn't want to play, so very tempted as I was to get some New Basket Filters, since I've got Six New Injectors coming, it didn't seem really worthwhile at least not yet
As it will probably cost me a nice meal out, in order to get the GF out of 'Smug Mode'
But looking on the bright side, it was almost certainly blocked injectors that was causing the problem and Jagboi you were right! they didn't burn out but as for Injector Number 6, I'm not too sure

No, the EBC4430 are for the earlier AJ6 engine. Totally different management system, so without doing some measurements I wouldn't mix.
I'm actually very surprised that the coils would burn out, that isn't common. I would expect that a set of 6 off ebay or a breaker like EuroJag from an X300 would work fine.

You were right they didn't burn out, as instead the Basket Filters were all blocked up with 'Crud' and when I pulled those Filters out, I got 5 out of 6 of them Spraying!
Number 6 though does not want to play!

If you have an ultrasonic cleaner, give then a min in that and see what happens. Probably just gummed up.
I have no measurements, but since the AJ6 uses a Lucas/Bosch ECU and the X300 is Nippondenso I wouldn't surprised if the resistance characteristics of the injectors were different. Jaguar changed the control systems completely between AJ6 and AJ16. Mechanically they are similar, electrically they are completely different.

I hate the updated browsing I posted in the wrong thread because I went to the end of this thread and the other was tacked on the bottom.
I posted a TSB for the AJ6/16 injectors here

Hi Jagboi
I put all the Injectors in the Ultrasonic Cleaner to Start with but still had to give them a bit of a 'Tap' with a Hammer although the 6th Injector is still refusing to Spray
So I left it in the Ultrasonic Cleaner overnight and am going to give it another try later on and just in case anyone mentions it, I have also tried back flushing and blowing it through with Carb Cleaner
Also when I get the New Injectors, I will check the Resistance and then report back
@Warrjon Thanks for the Pdf as that could be very useful

5% doesn't seem to bad, especially as the flow rate must be down on old Injectors when they start to get blocked up
