Stick a couple of fingers over the air intake on the burner to see if it fires. Don't block it just reduce the amount of air its pulling in.
Tried that but made no difference, pressed reset button again and let it start as normal and it started. I’m totally confused.......

Yeah think so, can see pump drawing oil, transformer is sending spark to electrode and then goes lockout.
From what I've seen, heard and read I'm still leaning towards a pump issue. I'm not saying it is but it's what I'd run a couple tests on first. To prove or disprove ignition and atomization things have to be done but I'm not going to say what. It could be air related as well but I'm not convinced.
I cant say anymore, from here on in it needs a decent engineer with good experience and the right gear.

Have you taken the burner out before?
If you have, take it out and take a picture looking down the blast tube. Make sure you unplug coil or turn it all off.

Ok no probs, thank you for your help.
Going to give someone local a ring tomorrow for advice before getting them to come visit.

No never taken burner out before. Although I work as a mechanical fitter im not confident with taking burner apart.
No problem, respect somebody who knows there limits.
Was the nozzle changed at the last service?
Whereabouts in the country are you?

Will give most things ago but know when I’m at my limits lol.
Yeah nozzle and filters was changed last service.
Im in Lincolnshire.
Yeah sure will. Hopefully if I get sorted I’ll be able to pass on my fix to someone else.

Bacon, sausage and egg butty???
Fool the photocell into seeing light once burner fires and see if burner continues to fire while photocell out. Handy on Sterling burners.
That will prove flame is poor for some reason or photocell had obstructed view.
Does sound like flame burn is barely making it

Boiler started up 1st attempt this morning.......
I did try this awhile ago. I think when I removed photocell burner continued running but when I covered photocell it shutdown if my memory serves me correctly.

Took burner unit off and had a look. I’ve attached photos. Tip of nozzle is damp with oil.
Any suggestions?

Combustion is most likely then poor if flame isn’t partly being obscured from photocell view.
But can have one of many causes.
Nozzle could be faulty, or air setting wrong or burner drawing in flue gases, or oil pump pressure is set wrong, are some possibilities.
Just a quick question, the capscrew that is in the main body of the burner just below the black plastic cover for the photo cell etc is that what is undone when boiler serviced? If so should the gasket be replaced?

could the electrode be causing the issue of lockout? If it’s not positioned correctly could the photocell fail to detect it sometimes?
is the blast tube ok or should that be cleaner?
The Alan key under the black cover is used to undo and remove the burner, you've detached the whole thing. The electrodes don't look right in terms of position and could be part of the reason it doesn't light sometimes, it doesn't explain why it sometimes ignites and then loses flame during 5 second safety time though.
That capscrew is seriously tight, should the gasket be replaced when burner is split?
wish id paid more attention to what he was doing when he serviced it.

I’ve contacted a 3 local heating engineers, 1 said he would go with pump bring issue. 1 said possibly pump but wouldn’t be sure and the other said it’s the control box.
