My boiler has starting making a strange noise for central heating only?

It was a loud tapping noise, i turned the boiler off an all the pressure had gone so i put the pressure back to 1 bar and bleed the radiators, a lot of air was in them,

But now i notice that the boiler will start up for a while the pilot light will light up but then after about 20 seconds it cuts its self out?
The pressure has stayed the same now at one bar.

Any ideas on this? and how much would it cost to fix?

Q: How much will it cost?

A: How much string do you want to buy? Prices depend on area, , how easily accessible your appliance is to access, what is needed, what other damage has been done... Way too many variables for a net based question.



Q: What's wrong with it?

A: I would suggest your pump has gone.
