Boiler problem

[Arron hannon]

I have been out to a baxi 105 he the boiler does not go to ignition for ch / dhw I have changed the aps as I know this is a main fault on these boilers but that didn't solve the problem. So I rang baxi told them the problem coz the boiler does not come up with a fault on the front panel they said it sounds like the pcb board so I have changed that and still no difference. There is no fault showing on the front so I have gone throw the checks.
power on = yes
gas on = yes
demand hw/ch = yes
Micro activated = yes
fan runs = yes
Pump runs = yes
Then doesn't go to ignition I have looked and looked the only thing I can think off now is the fan because it runs at its slower speed but when it goes to its faster speed just before it should go to ignition it stops then runs throw the cycle again. But no fault comes up on the board.
Anybody any answers for me thanks
