2006 S40 crank no start no fuel

[Sanel1279]

Hello everyone if someone can help plz do i have a problem child on my hands its a 2006 volvo S40 fwd it has a few issues my first one is no fuel pressure i exchanged 3 PEM boxes already and still no fuel to getting to the engine but when i power up the fuel pump directly with 12v via the PEM connector the fuel pump runs builds pressure up the car starts and runs for as long as the fuel pump is manually supplied with 12v power after i disconnect the 12v supply the car runs until it runs out fuel maybe 20-30 sec.

i also had a problem with the cabin fuse box it got wet and got corroded i took it out and cleaned the box as best as i could i also noticed that there were some burn spots on the connector and the plug i was wondering if i can just replace the fuse box with another used one and do i have to reprogram the new fuse box .....
