Swift Flow 75 - 80 Combi Boiler

I changed my Stop Cock and now my Swift Flow 75 - 80 Boiler will not work.

My boiler piolt light works, the fan kicks in when a tap is turned on or the heating system is turned on. all radiators are bled and all taps work, just no heat.

The Burner will not ignight, I've made no changes to the boiler only to to the house stop cock (cold supply)

i wouldnt think it has anything to do with the stop tap as the heating is not working to if it was just the hot water then it maybe.if its picking up hot water tap then its next sequence would be the fan. i would check the air pressure switch. hope this helps
