problem on a ideal classic lxff260

[nadia69]

i did a service to a ff260 and the fan was making a noise so i changed the fan , tried to start the boiler up and it wouldnt fire , so i changed the pressure switch it still wouldn't fire , i am only getting live to no and nc and not common ; i phoned ideal and they said check the flue etc everything is in order the flue casing seal looks ok and i have changed the pcb . i also changed the silicon tubes as one was perished but i used the clear silicon tubes and cut them to size would i have to use ideal red and blue tubes as the internal bore is smaller , when you suck on the negative tube the boiler fires , anybody got any clues ?
