Euro combi 13 yrs old won't fire up...Help?

Hi, My boiler stopped working this morning. no heating and no hot water. Turn on and boiler seems to begin start up but does not fire and safety cut off comes on. I can't see a pilot light but not sure if I should! Please advise.

moving house and just want to get it working again as new owners likely to be replacing boiler with new kitchen.

Any help you can give would be much appreciated. thanks
