Low fuel rail pressure issue please help

[Lp93]

Hi all. I'm hoping someone can help me out and point in the right direction

My e90 320D n47 2009...

So basically my e90 n47 won't start.

Mrs let the fuel run low (computor said 20miles left) and the engine cutout. She restarted straight away and got around a mile to the petrol station. After filling to just over 1/4 tank the car started but didn't run for very long at all, maybe 2 mins before it cut out again.

I then managed to get RAC to drag the car home. I scanned through the fault codes, and also took a readout for fuel rail pressure.

Rail pressure, actual ~ 80 bar
Rail pressure, specified ~ 454 bar

I have since managed to get it started while INSTA+ done a bleed on the fuel system.
It ran for 10 mins at 2k RPM but as soon as it had finished the bleed and let the idle drop to normal, it cut out again.

The codes I am getting I will list below.

004560
004570
004610
00483D
004b90

If anyone can please have an input of where I should be looking It would be massively appreciated!!

Thank you all in advance 😎

Those codes are just jibberish if you don't attach the description to go with it.

I am thinking that the HPFP is dead, just by looking at the rail pressure. The other thought is air compresses and it's blocking the HPFP from doing it's thing.
