I have had an Omega 2.5TD for about a year. This is the first diesel I have owned although very experienced with petrol engines. The problem is that over about the last few months and very slowly it has become more difficult to start. After waiting for the glow plug indicator to go out and starting to crank it is like one cylinder will fire but not the others. It is usually better to keep cranking than trying to wait for the glow plugs again. Eventually, and after lots of smoke from the exhaust, it is like another cylinder catches and then it starts.
After starting it runs normally and a restart when warm is ok.
Is this a glow plug problem in some way? Or something else?
Cheers

Two things worth checking and in this order.

1) Check the injector bleed off pipes, over time they perish and let air in.

2) Pop the fuel pump out of the tank and check the pickup filter.

In between showers I have had a chance to have a look....
There are some pipes that daisy chain from injector to injector and finally to somewhere..... These are all braid covered so it is difficult to see the state of the pipe material itself but I would have said they were ok. I gave some a tug to see if they were loose but seem ok.

So I had a look round the pump. After locating it in the boot & disconnecting the pipes and electrical connector I tried to get it out. I have the Haynes book on the Omega but of course it doesn't cover the diesel engine.... Anyway sort of unclipped it as the book suggests but the middle bit with the pump would only come up about 1/2" & no amount of jiggling would persuade it to come any further.

Had to stop there as was gone 9pm & starting to get dark....
Have to say I can't quite see the logic in it why would the fuel filter being blocked a bit affect startup when little fuel is needed versus full speed??

Change the glow plugs. I have a box of 6 for a TD. I also have a length of the braided pipe too, so let me know if you want them.

Remove inlet manifold to change glow plugs. Easy enough job.

removing fuel pump is easy when you know. thgere are three ratchet lugs on the inner rim of the housing. the whole white plastic housing should come out with the small pump in the middle, filetr is on the bottom.

Check also diesel filter in engine bay. Again I have one of these available.

Had similar problem
It wasn't the filter in the fuel pump but the actual pump was US
As a result the engine needed a lot of cranking to pull fuel through before it would fire, the pump in the tank primes the system

I have had an AA man look at the car and he is sure it is a glow plug problem. I did try to PM you but got no reply.
The question is what do you want for the glow plugs? I assume these are new??
