diesel lost power?

Just a general question, does diesel lose its power over time, kind of how petrol loses octane?
Got a car getting very difficult to start, engines just been rebuilt, pump timing is sound, as are glowplugs and injectors but the diesel has been sat in the tnk for near 4 months.

Yes it does!! You will have water from condensation in the tank as well. Assuming everything else is o.k., no air leaks, etc, if it does start fill it to the brim with fresh diesel, then run it dry, and change the fuel filter as wall, before the next fill.

its got a brand new filter but suppose I can change it again. There was only about 1.5 gallon left in the tank and it did start just not too easily. I have put another gallon of fresh diesel in there and also put some redex diesel treatment in, seems to be starting easier now. I will run it dry though then put clean filters in again.
How hard is it to flush a tank? Is it worth it? the car has seen 114k.
