To answer

Pete
Thanks for responding, the issue is still the same. No engagement of the new starter as well by key.

I did find that the large ground wire that is located on the engine mount, was stripped. It would finger tighten but with any torque at all is would strip out.

So moved this to the block onto what looked like a threaded bolt hole directly across from original.

But the issue remains. I was able to place a jumper across the SM relay and the starter turned the truck over but it does not start, nor "hit" as in try to start.
This all started when my key fob stopped working. As I was having an issue with something making a noise it was sitting waiting on money to go see a tranny shop. While I was frequently starting and letting the car run to charge up the battery every now and then, the fobs stopped working. Repaired the three green wires and the battery started to drain over nite. I was able to jump start it to get it in my driveway to work on it, but it just stopped turning over in any manner with a fully charged battery.

New starter works when using a jumper wire, but will not start with the key in position II.
I have checked all of the fuses, 40 amp SW this is the small clear top fuse where you can see the two solder drops, also switched out a known working relay to the SM relay, but no start.
Checked all of the wires in the area, all grounds in the area, and the alternator was charging when it stopped trying to start at all.

What should I do next? 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Ok I get you.

You could try turning the key to II, ensure it’s in park
And jumping the relay.

If it runs this proves the engine ecu is alive and ok which is useful to know.

The workflow is a bit complex.

One relay coil pin does the PN transmission
The other does the key Iii, imboliser, ecu, via fuses behind glovebox.

This is from memory and on a diesel.

There have been 2 similar cases on here.
One was a corroded wire under the relay fuse box
The other was a fuse behind glovebox (probably 5A at a guess, low value)

You need to test one coil pin goes to ground when in park or neutral
And the other coil pin goes to + when you crank the key round.

This is all from memory
And based on diesel !

I’ll try and see if the petrol looks the same when I get time

Having read more. It sounds imboliser.

Make sure the red led stops flashing when key turned to II

Have you a second key fob to try, just incase the one you are using is bad.

Latest attempt

So tried both keys with no luck.

There is a sound upon turning the key coming from over behind the fuse box but no idea what that is. Battery is at 11.06v so charging it up again.

LED Light? Are we talking about the light at the bottom of the speedometer that blinks red?
With both keys the light just continued to blink. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Yes that light.

Maybe someone could confirm it goes out when key at II

I've not seen it

I don't reckon I have ever noticed if it went out or not.

Also if this is the immobilizer, is that something I can DIY with my GAP Tool?
I did the three wire repair after my key stopped working the locks. Also replaced the battery in the remote, cause I thought the 3 splice wires may have let it go flat. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

It’s worth reading the codes. See if it points to imboliser.
Gap really needs one working key I think.

Charging battery

As GAP needs some volts I am charging it up right now.

Where is this 400 amp MEGA fuse and would that be indicated here, or does jumping the SM relay pretty much rule that out?
This all started when the sunroof got stuck open ans wouldn't close then its all went down hill from there. I may tear the CJB out and look behind the fuse box. At this point a stick of dynamite could be necessary.

I will try to find some codes asap. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Just went out to check. Certainly on my D3 Diesel the flashing red LED changes to solid red for around 1/2 a second on position 2 then goes off until key is back to position 1 or removed and only then starts to flash again. Must stop buying shiny toys....

Thanks for confirming led

The mega fuse is ruled out as bypassing the relay makes the starter move

So what's next I guess

Well I've checked the starter relay at R13 and guess I will start back tracing to the if i can find a faulty rely. I did find a burnt fuse at 49 I think of 43 somehow it supposed ly had to do with the key I guess. Well was hoping that would sort it but not happening.

I recently pulled the CJB so I know there is nothing there, unless it just happened during this battery starter issue. I can't see that happening.

It will need to be something other than the immobilizer I hope cause that would be the end of her, couldn't afford a large repair bill on this old a model.

So hope against hope its something I can find and not the immobilizer. 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

U0167-00 (68) Lost communication with vehicle immobiliser

All.

So I've been advertising my rover for parts and went out just because I was asked about what the vehicle did upon tuning the key. I did get some responses, and even more importantly I was able to connect to the Gap tool and get it up off the dump stops by adjusting the height.
While I read the codes I particularly saw this and was wondering if there is a immobilizer unit that can be plugged in under the shade tree, and see if that is my issue. If so I could delete the ad, as I would get it back under me to drive daily.

Has anyone been able to replace an immobilizer only, and not the CJB and Ignition, as I've heard?

Here are all the codes I got on the first key turn. I'm also hearing a relay click under the hood at the Engine bay fuse box.

REplacement Precision ECU plug n play or the ECU's+for sale

So I was trying to part the old girl out, but due to idiots asking questions I shuttered at turning her over to these people. I wanted to see if a replacement Plug and Play unit from Precision ECU, or the deal for sole on this board by Disco Mike?

Has anyone had experience with Precision ECU?

Disco Mik's deal:
2005 Discovery 3 TDV6 HSE Auto Cairns BlueDiscovery 3
[For Sale] ECU set, lock + barrel + 2 keys Report post

Removed from 07 EU4 car
2 keys, one key is less than 12 months old, and a genuine LR key. Showing 89k miles as per picture

ECUs included are:
Engine ECU
Transfer Case ECU
ABS ECU
Instrument Pack
Body Control Module
Ignition barrel
Passenger door lock
2x keys

£250 ono

So if I install the ECU, engine and the ignition barrel could I use these in my vehicle without programming at least anything more advanced than my GAP tool? 2005 Land Rover D3, 4.4L V8, Maya Gold Metallic
