can not get it to fire up

Does it try to light? (continual sparking) or not even try? If not trying, check fan pressure switch. If defective or wires off then boiler will not move to lighting stage. Dependent on year of boiler should have some leds in control box that light up as each part of firing sequence completes. check to see how far they go
