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.

Did you change the plastic coupling from pump to motor?

Really need to get the gauge on, even if you have to drop the burner out to get it on.

Any fuel in the tiger loop ?

Get yourself in the arms as well. Plenty of posts to qualify.

Have you got single pipe system from the oil tank ? Did you bleed the system ? Did you change any settings on the air shutter? I assume the right nozzle is installed.

Is there any flow from the oil tank ?

Changed the plastic coupling. And solenoid as always change them at the same time.
No oil at all in the tiger loop. Can't seem to get the system primed.

Will drop the burner out to get the gauge on, if I can.

Single pipe from tank to firevalve and then into tigerloop.

You will need to make sure you have got a steady oil flow. release the fuel bleed port and place a suitable container beneath.Put the programmer on to heating and hot water and allow the burner to run through to lockout.
wait a couple of minutes and reset the burner control box.
do it a couple of times or until a steady stream of oil, without air.
