Sealed system, no pressure registers, no heat 3rd floor.

[MasterPlumbersKeymaster]

i know there i possibly a simple solution to this problem bu I can not find it so need some help.

The boiler is in the basement, shows no pressure, but there is heat to rad in basement, ground foor, and first floor, but not on second floor.

Tried to bleed valves but nothing. Let ut a bit of air and then nothing else.

Help?

The pressure in the system is just low enough to keep water in the first floor and the gauge is probably too insensitive or broken to register it at 1/5 bar.
