ideal FF50 , when switching on, pump sounds to be running but gas doesn't fire up

operation is as follows. power to boiler. fan runs.air pressure switch makes. ignition sparks and pilot gas solenoid open. pilot lights. rectification occurs . main solenoid opens. house gets warm . this is an idiot proof boiler. wherever the process stops thats the fault
