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
