Fuel feed pressure Volvo d12

I had this same problem. For me the cause was plugged vent lines on both fuel tanks.

 

@nasriza Hello , I have a 2005 Volvo D12 a month ago the truck sometimes did start up fine sometimes i had to crank for like 30 seconds to start it and it was running rough on idle when you rev the gas a couple times it was running fine and also when the engine was warm it war starting and running fine but randomly while driving it was showing Check fuel filter in dash i did change the filters but still same problem the next day. Yesterday It started fine but was running very rough in idle and also in 1500 rpm white smoke was comming out of exhaust , i turned it off and now the truck doesn’t even start no more i tried with starting fluid it just cranks no start at all , has some codes Fuel feed pressure and FUELFEED PRIME OUTAGE.Mine has the electical primer i tried to prime it with the button on the dash but still same problem. Sometimes i get ECU CODES Water in fuel and Injector #1 , any idea what the problem can be?
