Was the engine crankng and not firing or simply not crankng.....it could be as simple as some water in the fuel....

It was cranking but not firing.I thought maybe there is some air in the fuel sistem.

When a diesel engine does not start, the first thing to check is always the glow plugs...

Taxi Driver (that's a user here) found that you can test glow plugs by checking their resistance - he did this on his Merc - so I suggest that you check this first.

Other causes for non-starting could be due to problems with the fuel pump or as suggested with the diesel oil.

From Taxi Driver's http://www.omegaowners.com/forum/YaBB.pl?num=1170450762/0#12 :

'So if any diesel omega owners are reading this.....then yes you can test the glow plugs by metering them.....open circuit they're knackered.....reading of about 0.5 ohm and they're ok'

Of course i checked the glow plugs-they are o.k.Today I changed fuel filter and one fuel pipe,maybe it would help.Tomorrow morning I will know it.

What about the fuel?  Did you refuel between start/stops?  Could be, given the extreme temperatures, that the diesel does not have sufficient winter additive and is waxing up, causing blockages.

I do not know if it is possible to bleed these systems but if you can, how about puting fresh fuel of known good winter quality in, bleeding through a new fuel filter and trying again?

As said, experience of these particular engines is nil but have worked with larger diesels over the years.
