Another thought. Have you ever cleaned the filter on the lift pump in the fuel tank?

ive been told by a vauxhall man that it does not have a lift pump in tank ? thanks ill look into it

I would have a look under the boot carpet for a circular access plate held by four screws.
I'll be surprised if the 2.2 doesn't have one but then mine's a 2.5

im going to have a nosey at it now , i guess it will be the same access plate for the fuel sender unit ,ill let you know. cheers

cant seem to loosen the big locking ring on top of tank to have a nosey at stand pipe filter any hints? also ive started the car (very hard) turned it around and faced it down my steep drive its still the same, so im thinking the fuel cant be running back up to the tank

There is a Vauxhall tool for undoing this, but carefull use of a piece of wood as a drift and a hammer will soon shift it.

yes i actually topped tank up with 25 quid as ive heard that because its not got a fuel pressure pump you need a good volume of fuel, as ive said ive had no luck even facing car down the drive ,today we gave it the slightest spray of easy start and it fired up instantly , this was so strange considering it never even tried to fire winding it up with the key cheers

I agree with Boditza. Try reading the codes. As far as I remember there are only 2 or 3 codes relevent to pre heating, as follows.
P 1694- Glow plug indicator lamp/ wiring fault
P 1694 - Has another explanation that I have forgotten, but it is associated with the Glow plug indicator lamp
P 1635 - Mal function in glow plug heating and control circuits.

The first is pretty self explanitory and the third can account for one or more glow plugs open circuit, wiring problems or glow plug control module fubared or just about any other pre heater malfunction other than the indicator bulb/ wiring.

It is not unknown to have all four glow plugs fubared and the car will still start quite easilly in warm weather. They are easy to test - pull off the caps (they have a release clip) and they should read about 1 ohm tested to earth in situ with a meter. If you have any that are higher resistance they are fubared.

Glow plug control module sits in the big black triagular plastic box on top of your battery.You are looking for a finned aluminium box about 9cm by 4cm right in the bottom of the triangular box. Part is common to several GM cars and is often held in stock by a decent dealer. GM# 55354141

IIRC you have changed the battery, so will have disturbed this module? It may be worth getting it out and checking all contacts are good, but see what the codes indicate first. When I had this problem I noticed that on distrurbing this plastic box, my starting problem disappeared, but returned a week later.

PS 2.2Dti has no lift pump

Park it on a hill and keep the tank 1/3rd full? Surely not part of the original design brief Tongue

I only know a bit about my old volvo penta and having checked the glow plugs I would next slacken the union where fuel feeds to the injectors to see if fuel pushes out when you crank it. Whether thats feasible on on Omega I don't know. Beware it should be under some pressure.

Might be worth a call to someone like this? http://www.ecutesting.com/vauxhall_bosch_vp44_diesel_pum.html

(

you have the diesel feed and return pipes and a cicular access plate thats welded onto the tank with rust and a locking ring which so far i cant move,this gives access to the fuel gauge sender unit and stand pipe which i assume has a small fine mesh on it, never the less i think if the mesh was dirty it would cause fuel starvation as in no power or lack of acceleration rather than a starting problem like this, cheers
