You clearly have no idea what you're doing. Bite the bullet and call someone who does.

Best to get someone out to have a look, could possibly be the Air Pressure Switch

Could be one of about three controls that is preventing it from firing, one of which (as previously mentioned) could be the APS. These controls, however, are safety devices for the boiler and as such should be tested by an RGI to ensure safe operation of the boiler.

fitted a new pcb

Check you have put all the connections on correcttly, especially the yellow and orange wires on the right terminals

These boards are a bloody nuisance to fit as baxi says check connection are still pushed firmly on . Also it sometimes takes turning power on and off a few times for them to work properly.
Could be an expensive mis diagnosis at around 125 quid for a board

thanks for the advice

dont worry,i wont be messing with any gas related items.

was hoping there might be a known fault with these boilers(other than pcb).
