there is a bleed on the oil pump pressure test point, but be careful if you don't know what you are doing and "undo" the wrong connection you could adjust the pump pressure and need a tech anyway

If your tank is above the burner, slacken the nut where the flexy braided pipe enters the pump and allow kero to bleed through. Failing that, theres a bleed valve closed with an allen screw, so slacken that when the burner is trying to start. Don't adjust the one with the screwdriver slot with the big nut behind!
Post a pic of the pump if you like.

Undo the lower of the two plugs.....don't touch the upper one - that's the pressure adjustment screw.
The lower plug is undone to connect a pressure gauge when setting the burner up.

Oil pump sounds like its seized.
Does it rotate freely?

Just managed to see the video......
Got to be right there, Terry - doesn't sound like anything is spinning at all. Fuel dripping too?

Get someone in who knows what they're doing.

how can i check for pump running freely? i appreciate your help with this.
also can a seized pump be fixed or does that require a new one?

its not my boiler- belongs to a friend (single mother private tenant) - landlord wont come to look because house is in process of being recovered by bank. the girl has another 4-8 weeks tenancy left. im just seeking to help maybe keep it going at as little cost as possible ,

 

[cornishgas]

You need an oil pressure gauge to check the pump is running freely and stable, then set the pressure to the correct setting and then put a flue gas analyser on it to get the correct CO2. The boiler if not set up correctly can produce excess carbon monoxide and be a death trap. Get someone in and deduct it from the last rental payment.

You said you have removed the pump for cleaning....it should be easy to turn the pump shaft by hand, and it shouldn't have any tight spots as you do so.
Its possible to remount the pump slightly out of alignment, so the motor finds it difficult to spin. Try slackening the motor mounting screws just a touch and try again.
If the pump has tightened up, I'm afraid its game over - it needs a new one.
