What about the stop start system, which incidentally has never worked, could that have a bearing?
So If it starts up ok when bump starting you’re doing away with the starter switch, wiring and motor etc. Could indicate a volt drop somewhere being caused by the starter circuit.

I would doubt it tbh as you’re really only using the clutch switch circuit as a starter circuit. I think there’s also mileage in WS suggestion of giving it a sniff of easy start.
Any update on this OP?
Not much of an update I’m afraid. Still not fixed. New battery, crank sensor, cam sensor and throttle body. No change, exactly the same except the stop start is now working (battery sorted that) which is a bit annoying as when you forget to turn it off and the bloody thing stops at the lights it’s a bit embarrassing when it turns over that long to restart the lights have gone back to red and a dozen cars are pomping their horn at you!
I’ve given up now and booked it into RR main dealer for a diagnosis, but they can’t look at it until the 24th.
It’s so infuriating because it is such a good driver and to be fair it’s never not started just takes forever turning over before it does. Bloody starter motor is going to be worn out next 😟
Maybe I need a drive down to Wiltshire and leave it with you frankie
My wife often comments on how nice Range Rovers look and how she would like one. Of all the 4x4's a RR is the I would love to have - looks and driving - but it is stories like this along with the general languishing of RR at/towards the bottom of reliability tables means that it's never, ever going to happen. Such a shame.
Kelley is loving the Kia in the snow Neil, thanks again.
Last 3 cars have been JLR and no real problems with any of them. Evoque, E-Pace and F-Pace.
Started out with nothing. Still have most of it left.
Yes, I realise that, in fact, the majority (maybe a slim majority) of owners don't have issues with JLR vehicles - but too sizeable a minority for my liking do. Where I live, I'm surrounded by JLR (and BMW, Mercedes and Audi) vehicles that make my Honda Civic look a little sad but, perhaps to my cost, I put reliability above practically everything else in cars.
Have they all been bought from new and changed after a few years though?
I think the problems ( only a generalised observation) start a few years down the line, out of warranty, lots of things seem to happen then.
Cheers..

Ok stop rubbing it in :)
Yes, Evoque MY16, E-Pace MY18 and F-Pace MY20. You may be right about older ones. Although had a Freelander 1.8 for 5 years around 2001 and the damn thing just wouldn't blow up! Had all the hairdresser comments from the Disco, Shogun and Hi-Lux boys! Never got stuck anywhere on my permissions though even on some of the really slippy stuff. No ploughed fields though!

Bugger!
I literally have no idea what’s causing your issue, there’s so many possibilities but from everything you’ve done and said it really is a mystery.
Someone said the other day about a one way valve to stop leak back, the Evoque does have this in the spill rail return, it’s designed to hold pressure of up to 145 psi in the injectors but you’re issue happens almost straight away after switch off, there’s not much time there for the system to lose pressure.
The other puzzling thing is that there’s no bloody fault codes, all Land Rovers throw up fault codes at the drop of a hat.
When they find the issue can you update the thread....would be really interested to know what’s causing this.
You said a throttle body was fitted....did you do this?

What about a sticky injector that is taking time to reseat ?

Ralph Waldo Emerson: We ask for long life, but 'tis deep life, or noble moments that signify. Let the measure of time be spiritual, not mechanical.
Possibly, however an open injector would normally lose pressure in the common rail and it would fail to start all together.
Low pressure in tank pump struggling? It works it’s hardest during starting - apart from starting the high pressure system can pretty much cope without the feed pump
It doesn’t have a conventional in tank fuel pump that supplies fuel to the engine. The fuel is drawn from the tank to the high pressure pump by a lift pump which is integral to the high pressure pump. The pump in the tank only transfers fuel from one side of the saddle tank to the other side pick up.
The in tank pump does apply positive pressure to the HP side - not just transfer across the saddle tank
As said above the only time this pressure is really needed is during the peak pressure of starting but it is needed then
The only purpose of the intank pump on a RRE is to transfer fuel that’s it. The intank pump doesn’t supply fuel to the HP pump
I remember the old E39 5series diesel used to have this set up and would give this problem if the fuel level went below a quarter tank,just a thought.
If you want luxury + reliability then Lexus is something to look at. I was seduced away from them by a wanton convertible Mercedes but still sneakily look at them on autotrader.
I wonder if it might be a function of the fuel filter element despite the replacement(s).
Are you able to remove the filter element from its housing (they sometimes "open" by twisting them apart ?)
If not, are you able to take the filter out of line - by way of larger diameter tube with a couple of jubilee clips ?
If the resulting "free" flow allows an immediate start it would suggest either -
1) Sub standard / out of spec / too much "filter" fuel filter or
2) Sub optimal fuel pump performance (the under bonnet pump) - inability to overcome the effect of the filter.
I know it's a long shot - but the tests should only take you five minutes and won't cost you anything.
Assuming that you have access to decades of useless motoring tat in your garage : )
Good luck, in any event.
OP, due you have an update since the car’s visit to the dealer?
Sorry for the delay in updating but I had to cool down a little in case I said something slanderous.
Car went to main LR dealer, Inchcape in Preston. Big operation in new multi million £ purpose built building.
When I booked it in I asked if they did a fixed fee fault diagnostic. Yes they said, £96.00. We will find the problem, we have the most up to date factory approved test equipment and factory trained technicians. I qualified 3 times with them that the fixed fee would cover finding the problem regardless of the time they spent on it. Yes was their answer and we will then advise the cost to repair before we do any work and you can decide if you want us to do it or take it elsewhere. They rang me a week before the booking to confirm and I again confirmed with them they would doing a fault diagnosis.
Dropped the car of with them at 8.45am as requested and at 4.30pm I hadn’t heard anything. Rang them and was told car was ready and could pick it up. When I got there car was parked in car park. Service assistant met me outside (COVID restrictions) and gave me an envelope and the key. What is the fault? I asked. A full report is in the envelope I was told.
The report, and I quote-
Investigated bad starting/long cranking period. 1 injector looks like it’s leaking. Suggest taking car to a diesel specialist for testing and recalibration.
Complementary health check performed and vehicle requires new discs and brake pads to front and rear plus both front tyres require replacing. This work will cost £1547.00
Which injector is leaking?, how did they test it?, what other tests did they do? Is that the cause of the problem? Apparently they don’t have the equipment to test anything on the injector side. They were Quite happy that they didn’t find the fault they were supposed to, but would be happy to take £1500 off me for brakes and tyres that it doesn’t need. To top it all the car interior was left with nasty oil stains on the seat, steering wheel and centre armrest lid.
Complete waste of time.
Back to square one. I Will be doing a leak back test on the injectors next week but I’m not convinced the problem is there.
Any more thoughts out there? The fault started without warning. No problems, next morning problem. No build up, no did it odd times then got worse. The car runs brand new. No smells, no power loss, no hesitation, nothing. Just takes 8 or 9 seconds turning over before it starts. Every time even after stopping for just a few seconds.

Really helpful that!
Id be asking how they got to the opinion that it was injector related, unless they’ve already done some kind of spill they would almost certainly be looking at the injector/cylinder correction adjustment data for each individual cylinder. If you had an issue with a particular cylinder or injector its common to see a greater correction on the faulty cylinder. The fact they haven’t told you this vital information is probably because they’re taking a punt based on experience rather than fact.
I would have hoped they would have looked at fuel pressures, sensor signals and voltages under cranking and a whole host of other stuff. The fact they’re unwilling to stick their neck on the block suggests that it’s just a guess.
Sorry, completely forgot about updating the thread.
After the RR dealer nonsense we started looking at the injectors, taking off the leak pipes to see if one of the injectors were leaking. No joy, all seemed fine, however in a moment of desperation decided to remove all 4 injectors and send off for testing. One was well out of range and the other 3 were faulty (surprisingly!). Rather than just change the one obviously 'more' faulty, 4 new injectors fitted.
Problem solved, working as it should, starting on half a crank.
Not a cheap fix as the injectors were £150ish a piece. Still happy wife, happy life. She's back in love with it and off my back. It didn't go down to well when I suggested she should use the Austin A30 :) .Couple of months now and still running spot on.
Thanks for everyone's input.
Neil
Interesting and very strange at the same time. Very strange to have 3 out of 4 injectors faulting without some previous. Think I asked you before it had been misfueled and you confirmed not since your ownership.....my guess is misfueling before you owned it has caused this.
Glad you eventually got it sorted.
