It does attempt to fire up yes, maybe 5 seconds in goes back to lockout. I can get the boiler actually working by continuously clicking lock out one after another and it eventually does start running, then after few hours just goes back to lock out

Does sound like a photocell, but could also be a few other things. When was the last time it was serviced
It was cleaned out only couple months ago
But serviced?????

Sorry for my lack of knowing, what’s the difference? There was a lot of black sut that was cleaned out etc, but not sure what would be included in a service
What burner does it have? Does the burner sit on top of the boiler or at the bottom
The burners at the top
If you can remove the burner you can check the electrode gap yourself should be 4 to 5mm, my 17 year old Firebird gap is 4.5mm, the photo in post#17 (not yours) seems to show a enormous gap if those are the electrodes positioned at 5 oclock.
Haven’t got round to taking burner off myself etc, but a couple more things, I got the boiler working (just by clicking lockout and it eventually fires up) I washed the pots and had a shower and by that time it has gone off again
I'd be looking at a dirty blast tube first, then I'd be moving on to oil supply and oil pump
That had been cleaned mate I’m sure
In all of this thread, no-one has mentioned a nozzle. The black soot cleaned out a 'couple of months ago' is indicative of poor combustion. When serviced properly the oil pressure should have been checked and if dirty, the nozzle changed. If a dirty nozzle has been cleaned, it is possible that the spray pattern has been deformed by soot pressed into the orifice, or even the spinner inside not spinning so no atomised spray.
As i said before when was it serviced?

No it hasn’t been serviced in atleast the year and half I’ve lived in the house, before then I couldn’t tell you either
