3. check MP steam pressure which drives the ejector (is it according to the required pressure)??
4. check ejector drain and steam trap which send the condensate back to condenser (plug-up or not)??
5. check if someone has opened chest valve / valve after governor drain, maybe drain valve is open instead of steam trap, because condensate which goes back to condenser should pass steam trap, not through drain.
6. check your vacuum breaker is not in service
7. check level of condenser, it should be good, and check temperature of cooling water for condenser, it should be low enough to condenser steam

this is a valuable threads , at our plant I had faced such this problem , we were filling the water box with cooling water , and started the water box vacuum pump , but the level of water box didn't increase up , after searching around the condenser , we found an air leakage near the outlet flange of the water box at condenser outlet.
it could be a leakage from flanges around the condenser , or need the condenser to be cleaned again.
