      Possibly bleeding fuel pressure back to the tank from the rail. Then when you try start it a couple of times the pressure is built back up. Could be something stuck in the fuel pressure regulator or it is worn. Or a worn check valve on the supply side. I'm 5000k from mine so can't look at the engine to describe the actual components or fuel system, so I'm just going on basic common rail diesel systems.
      2001 V70 - 2000 miles from the nearest dealer and 3000 miles from home, used as my DD for work and storage when I go home for a couple of weeks.
      2009 XC70 D5 - bought because it was ridiculously cheap, cheapest on the planet, after the first drive the wife claimed it before we got home.
