    It can only be one of two things (I stand to be corrected!) either a blocked nossle (replace nossle) provided you are getting oil at the pump and it sprays (at bleed nut) when it tries to fire or it's a faulty photocell. Nossle approx €6 photocell RDB €22 max.

    Yea, if there is pressure at the bleed nut under the pressure adjustment screw (which should be about 15 half turns out from fully in), then the pump seems to be working. Try changing the nozzle for the same size and angle.

    When you switch on, you should hear the motor whirring, then after 10 secs or so, there is a click and a light buzzing sound comes in for about 5 secs, and the burner should fire during this time. I have heard of some RDB photocells giving trouble - I don't think that it happens a lot. You could carefully lift out the burner as it tries to start and see if oil is spraying from the jet but not igniting. You didn't move the electrides cleaning the nozzle or anything like that ?
