That's really annoying.
Did you clean the connections on the hp fuel rail pressure sensor and the lp one?

I have clean just the hp one (and i ended up without the rubber protection for that one). I will clean tomorrow both of them again and see.

Worth repeating the lp sensor voltage tests to see if it is telling the truth now the pressure is correct.

I will do tomorrow that test again and see. Today i am too tired...

Hi. I've done measurements again:
Pin 3 : 4.2v at idle and 3.7v at 3000 rpm throttle.
I have cleaned both plugs/sensors. Same problem.

So you have the correct pressure now. Looks like the sensor is responding OK and shows higher pressure.
Only other thing I can think of is a bad wire to the hp sensor. There is a replacement loom but you can check the resistance from sensor back to the engine ecu.
Nothing else left !!

so .. once the engine has warmed up , then you get the dash warning [?]
question :
on start up .. does it take much more cranking with a warm/hot engine,
than it does with a stone cold engine ?
if so ..... that could point to a worn hp.pump.

HP pressure check again ???
The LP is certainly fine now. HP loom is evidently a weakness.

Hi. The hp sensor it's the one on the injector fuel ramp?

What do you mean with "check resistance from sensor back to the engine ecu"? I don't understand this terms and please tell me how can i do this.

The hp sensor is on the end of the injector fuel rail. Near the battery but on the end of the pipe work.
I mean to check that the 3 wires in the plug on the sensor are actually connected to the ecu and are not bad resistance, so partly broken or damaged.
An Ohm meter between the plug and the ecu connector will tell you.
I don't know the ecu connections but will look them up if you don't have them.
