At the risk of sounding stupid, is it one of them models you need to tell the system it’s had a new battery and ‘code’ it in?

Hey all, little update, I went to a LR garage today as I was passing and chatted to a technician. Really nice guy, he seemed to think the likelihood of it being ECU related was unlikely, he said in his experience it’s usually the fuel pump that’s next to the fuel tank behind a little inspection panel. he printed a diagram off for me, have attached to this post. Has also given me a test to do to confirm his prediction (pull out a hose from the fuel filter, then the Ignition on but don’t start the car and see how much fuel comes out) … let’s see if this revelation takes me anywhere

Had that go on mine and a slight wake up call from a small hammer got it going enough to get me to the local indi garage who fortunately had one in stock along with a spare ramp for me to chuck it on.Hey all, little update, I went to a LR garage today as I was passing and chatted to a technician.

Was it easy to get to? My RR is currently in lowered suspension mode which makes getting under it a little more tricky.

It was easy for me cos I was using a 4 post lift but unless you're very very skinny I doubt you'd get under it. Maybe jacking it up and using axle stands is an option.

No way I would rely on the air suspension when going under the car.

Have you checked the fuel pressure yet?
Fuel pressure regulator is a fairly common fault.
The low pressure system pressure is approx. 1.5 bar to 5 bar and return end < 0.6 bar. The pressure in the high
pressure end is 200 bar to 1350 bar.

I need a proper diag for that right? Or is there another way? Thanks

My Foxwell reads them but no idea about what you are using.

I think mine does, will try it tomorrow
I have a 2006 TD6 with starting issues as well.
No code reader can access the ecu to read data but a basic generic code reader will drag error codes off it.
All of them come up with link errors.
Maybe try the generic obd2 error code function of the diag kit to see if errors are present?
My non starts were initially down to dodgy crank and cam sensors.
A faulty Crank sensor very very rarely kicks up an error code.
Another issue at the moment which I need to look into with air getting into the system so think that's one or both pumps in/by the tank causing this.
Also if the pressure sensor on top of the fuel filter is iffy it won't fire up.

I think mine does, but
good luck! Hopefully we can both get sorted , I have the same link error with my reader

Which ones have you tried?
Up to now, t
Icarsoft JLR version
Autocom/delphi
Topdon
Otofix
Various ELM327 based software
Britools (I keep spelling that wrong) version of the LR software/hardware
All give link errors or freeze up when I try to read live engine data.
The only bit I can do is read and clear error codes on the ones that have generic obd2 functions.
They access all the other modules in the car just fine as well, even calibrated suspension with the otofix one.
Apart from that problem reading live data which is similat to the OPs problem, it all works fine.
That's how I managed to get the error codes for the camshaft sensor, crankshaft sensor was just down to noticing the rev counter didn't twitch whilst cranking but never noticed it since but was the right solution anyway.
