Just did the paperclip test, code 19 stored, looks like a crank sensor then!

Read codes again and post.

Sounds very simaliar to my prevoius troubles  with the other omega, Changed the mass air flow sensor with a 2nd hand one and off we went without any further troubles

Engine can be started with Maf sensor disconnected for testing purposes.

Just home now, the car is still Fubar'd, code 19 was still stored in it when I did the paperclip test so got my mate to read it with his Snap-on code reader and clear the code. Once he did this it started no problem and ran for a good 5-10 mins then cut out again, no codes stored, restarted no problem then cut out again, no codes stored again. The warmer the engine became the harder it was to start, then eventually it wouldnt start at all but still no codes stored. Any ideas what to try next guys?

did your car get a new crank sensor? If yes was  it a GM sensor or a generic?

Have you disconnected the maf sensor as suggested by kneepad? Definitely not anything 'old school' like fuel starvation, by the sounds of things its some electronic jiggery-pokerey, such as the maf.

as well as the above advice I'd check battery voltage & whether or not alternator is keeping it charged. Also wouldn't hurt to stick a new set of plugs in  ;) Like kneepad says it'll run with or without MAF sensor & you've already changed crank sensor with no further codes. I'd say back to basics... forget it's a V6 and check all the basics; alternator, battery? do your lights dim with higher rpm? (I'd replace it anyway) & new plugs :y

I will check all the basics today and see what I can come up with, just frustrating cos I know it has to be something simple. Another thing I noticed was if you allowed the car to freewheel backwards a couple of feet then tried to start it in gear whilst it was moving 9 time out of 10 it would fire and run for about 30 secs then cut out again.

Id be inclined to ask if one of the omega experts is close to you and get them to see.

Is it possible that this could be something to do with the key losing its code as I had the car battery disconnected?

It's the chip in the key that talks to the imobiliser, check it's still there if  you've had the key apart.
