I have an external oil fired grant boiler. I have just fitted a new oil pump and bled the system but the boiler fires up for 3 seconds and then cuts out. any ideas???

Hello Peter
Do you have the necessary equipment to set the correct pressure on the oil pump?

Oil pump gauge?
Analyser?

Then stop messing around with something that could kill you or your family.

Hello Simon, you stole my next post to the OP! As you said get someone in who knows what they are doing. Oil boilers can produce a lot of CO and need to be set up correctly by someone who knows what they are doing.

Too many idiots think it's only gas that's a problem.

We hear it all the time. I found today we were competing against a postman for an install of an oil boiler! Luckily the Customer had some sense and we got the job. Frightening really.
