have you run out of oil recently?
could the burner pump be air locked?

have you tried pressing the rest butoon (red lit button) on the burner see if it fires.....

if it does but locks out (button lits again) you will need to come back with more detail (ie...it ran for 12 secs, then stopped, or ran and fired, then stopped...etc)
