you could also try with a bucket filled with oil and using that as the tank if you like...just to see whether it's related to a supply issue

Fire valve closed???

Went to the above boiler to do a service as requested but I stupidly forgot to test fire it before I pulled it apart.

Gave it a clean out, new nozzle and new oil lines.
Then when I fired it up it was stop start stop start then eventually locked out.
Checked the oil tank and there is plenty of oil and no contamination. (Brand new filter)

cant get any pump pressure. So changed the oil pump.
New oil pump fitted (although doesn't seem to be the exact same model even though part numbers are right as it's not got pressure and vacuum ports on the front.
Still the same.

Swapped the tiger loop (above burner) over quickly and still locking out. Just can't get any oil through it.
Cant check the pump pressure though as the test port is on the underside of the new oil pump.

Am I being really thick as it must be something really simple. Just every time I go there it's like 5-6 at night and dark and my brain is frazzled.

Cheers for any suggestions.

Any update on that ?

Finally got back to this one. Fitted the correct oil pump. Changed a hose that was sucking in air and she is running like a goodun.
