Freelander 2 (LR2) Freelander 2 it doesn't start

Hi everyone, I am the owner of a Freelander 2 2007 TD4 Automatic.
I have a problem, the car stopped working (engine power reduction) I got the message 0 autonomy, then reappeared normal autonomy but no longer starts. Went to a Mechanic for a week but he told me to take it in because he can't find what the problem is. On the diagnostics I get P0087 Fuel rail/system pressure too low. I checked to see if the diesel is getting to the fuel filter and it is not. I tried to start the engine with spray start, it starts but stops immediately. After several checks, including at the fuel pump in the Tank, where it seems that only a maximum of 5v current reaches? Can it be BCM? I am attaching a screenshot here. I am waiting for some opinions from the most knowledgeable. Thank you in advance.

When was the fuel filter last change, they can get blocked after a time and really should be changed every 2 years.

Hi Arctic2, yes, the diesel filter was always changed once every 2 oil changes, i.e. every 20,000 km. Unfortunately, the diesel does not reach the filter.

Tank empty or blockage in tank, no fuel pump in tank iirc

HI Deni75
Did you find a solution to your problem if so do please let us know.

Loose chip in key meant that the immobiliser couldn't be deactivated. Blue tack resolved the issue.
