Have you checked the obvious like spark gap, electrode, strike point, earthing, HT lead, etc

I have checked all items you detailed and even had a friend of mine take a look at it. This friend works on gas appliances only. I hope to have another look at it over the next day or so.

I have got this boiler firing. The 2 "new"PCBs which I had purchased were both faulty. I got my hands on a used working PCB and fitted this and the boiler fired up. Thanks to all who responded to this tread.

I seem to remember the white sparking lead is no longer obtainable. Not sure if generic ones will work

I was able to purchase a white lead which worked.
