Freelander 1 Injector Replacement! Any prerequisites required?

Hard Drive · May 6, 2020

Can anyone help with the following question?

If I fit a reconditioned set of Injectors (the correct spec for my car) what must be done to get them working?
I’m aware they do not need programming as it’s a 2005 FL1 Td4, but might there need to be something done for the ECU to recognise them, or are they a Plug’n-play kind of thing?
Any information will be helpful.

And I’ll add that yesterday, I fitted 3 replacement Injectors (known to work) but the engine failed to run at all. Not even a pop. The engine does run and did so when I refitted the originals.
And my reasoning for fitting new injectors? I'm going through a process of elimination in my attempts to correct a P1190 fault code. It should also make my car more reliable for future travel.

TD4 requires no code or any mod to change injectors.

Always use new copper washer and rubber O ring on the injector body as gasses will pass if worn or compressed.

Injectors for a manual and auto have different codes but both work. I have done it. My manual set work well with my auto box!!!

Thanks Andy. I'm guessing there must be something wrong with the three replacements I tried.
My recon set is due soon so hope they work.
Thanks again.

I've always wondered if that would be the case. Any noticeable difference in running, throttle response or gear changes?

No, drives the same. Better mpg in my view. Only did it cos the engine came from a manual donor car. Engine ran well so leave well alone I say!!!

With that fault code and the seemingly intermittent nature of the fault, don't rule out the hp fuel sensor connections and the hp fuel regulator connections or sensors.

Thanks Andy. I had checked these connections as well as replacing the fuel regulator with new seals. But nothing wrong was found - sadly. The car is now with a garage so they can try their wizardry on it. I've run out of spells and parts.

OK. Don't forget to update thread with the fix details!!!! We await with anticipation.

Landy Zone will be the first to learn what has caused me so much grief and costs. In the hope it might help others.
I'll keep you posted... in CAPITAL letters.

The latest news from my garage repair follows.
After replacing most sensors, both pumps & filters, checking this-and-that, the garage is pointing the finger at the Turbo. I, myself, had considered this too, and had already printed the procedure for replacing one as well as pricing a replacement. I didn't want to go to another unnecessary expense though, relying on my garage to offer a diagnosis.
It seems the milking computerised system that monitored my car indicated it was being choked. Which is to say, there was not enough air getting through to the engine, hence it cutting out above 2k revs. It was strangled, basically.
Monday will conclude what needs to be done.
But this will give some individuals a possible answer to P1190.
I was also informed my fuel feed system was working perfectly. I did use the phrase, 'Red-Herring' previously. And that's how it might be.
I'll write more next week.
I need to add, I did a test on my Turbo and it suggested there might have been a problem. You could try this yourself - although how relevant this is still has to be evaluated.
I isolated the vacuum hose to the Turbo Solenoid -blocking it so the brakes, etc, would be unaffected. This action prevented the Turbo from kicking in. I heard a loud howl from the Turbo area when I ran the car, something I've never heard before, its intensity altered with the revs.
It was as if the exhaust-driven Turbo-fan was struggling to rotate. Maybe yes, perhaps no. It's a thought though, and perhaps testing if you too have a P1190 fault code.

You'll of course not be paying the garage for all the stuff that they have changed that has not cured the fault.........

Sounds like the only wizardry they have injected so far is a huge bill for unnecessary new parts!!

Hi Andy. I've read what you wrote and the garage has not fitted anything as of yet. I didn't do a good job of writing the last report, which was misleading. My bad.
In point of fact, I have replaced all the sensors, fuel pumps, filters and refurbished the Injectors myself. Checked wiring and soldered terminals to prevent poor contact.
What the garage has done, so far, is to give the car a visual once-over, started the engine - where it was instantly recognised the engine was not as smooth or responsive as it should be.
Then the diagnostics were connected and the car thoroughly tested. What shows is gross air starvation. The diagnostics have been sent to Edinburgh, where they will be extensively analysed.
In the meantime, my garage will disconnect the exhaust manifold from the Turbo before checking for any excessive play on the fans.
I'm not a great fan of garages, but this one has my trust & respect. And that is not given easily.
I'll keep ya'll informed.

I would still strongly suggest that the exhaust system and particularly the catalytic converter be checked for restrictions.

Thanks again, Paul. I'll mention this to the crew at the garage, insisting they do it.

andyfreelandy · May 10, 2020

My apologies, I did read it twice before posting but it looked like another 'change everything' garage!!!! I have seen and encountered so many it is sickening. Good luck with the fix.

Hard Drive · May 10, 2020

No need for appologies, I badly wrote it.
the garage in quedtion is doing it's best to keep costs down, thankfully.
