D4 3.0 TDV6 will not start. Advice needed

I have a 2010 D4 3.0TDV6 auto which has done 80K miles.
I was driving at approximately 30mph and the engine just stopped for no reason and would not re-start.
It would crank over but not fire up.
I read my fault codes and it came up with P0087 low fuel pressure code, along with another load of random codes..
My schrader valve was showing weak fuel pressure when checked.

I have since replaced my LPFP with a brand new VDO module.
I have now replaced by battery with a brand new Varta one.
My car now cranks over, but still will not fire up.
I have strong fuel pressure at the schrader valve.
I am not showing any fault codes now when I read them.
I can not find any fuses that have blown.

Any idea what to look for next would be appreciated.

Take the oil filter out and check for metal in it ?

Cam belt kit, injector pump belt kit, pulleys water pump, fuel filter housing assembly were all changed 13th Feb this year by my trusted indie.

After doing a bit of online research here, checking over my service history, call to the local LR dealer who originally sold the car, etc, I'm thinking it could possibly be crank position sensor failure.

The VIN number falls within the LR re-call from many years ago, but it can not be confirmed if it was changed on the re-call. LR dealer has a recall document on file from 2013, but they can no longer open it up to see the content.

My local LR dealer need's to check with Land Rover UK on Monday to see if they have official confirmation.

As for the oil filter, I have not taken it off to check for any catastrophic failure yet. I'm praying its not.
It turns over freely without making any noise, it just does not fire up as it would normally.

Any further thoughts on the crank position sensor failure would be appreciated.
Kind regards

What scan tool are you using? Can you read measured values? Does the high pressure fuel actual value meet the specified value?

@Mastertech, thank you for your reply.

Im using an AUTEL AP200 scan tool.
I think the Autel does capture measured values.

A friend is dropping off his all singing & dancing Snap On scan device later today for me to utilise.
What should the high pressure fuel value be to allow the injectors to work.

I'm also going to fit a new fuel filter as well, even though the current one has done 800 miles since all the belts were changed.

I know this was originally posted several months ago but I recently had exactly the same issues as the original poster.
It started with the engine cutting out at a junction and restarting after several attempts, it then ran perfectly for about 3 weeks, then the engine cut out while driving, I was able to pull over and it started and ran perfectly for the rest of the day. It got to the point where it became impossible to start, the only message on the dash showed a red battery warning, the IID always showed no faults! I replaced the starter motor and earth straps and it started instantly, it then started the same problems again, I replaced the alternator and all was well again for one week then it became impossible to start!

I decided to try the IID again and it came up with no faults but after letting the engine turn over continuously for about 10 - 15 seconds it came up with crankshaft sensor fault!

After looking at changing the sensor I decided to book the car into a local Land Rover Indy, they confirmed from their diagnostic test the sensor was faulty and said it was a pig of a job to do!!

I am 76 years old and have never put a car into a garage for any fault, but looking at that job I think its time to consider handing the difficult jobs over to the professionals!

I have not got the car back yet so keeping my fingers crossed its fixed.

Sorry for the late reply.
I eventually got to the bottom of the problem.
My HP fuel pump on the engine failed catastrophically.
Required a new pump, fuel pump belt kit again, both fuel rails, 6 x injectors and various other bits.
It wasn't a cheap fix.
Fingers crossed this hasn't happened to your vehicle.
