Oh dear. I suppose there's just a chance the 'fault' was upstream of the actual engine.
BO0M, Is there an improved check or automation for those fuel pump switches above the skipper's head? In my time on type I couldn't believe how many times the NFP failed to set them. I heard of at least two times it lead to a Mayday being put out.
(as an aside, I couldn't believe it wasn't part of the engine fire drill to turn them off. Just one example of FCOM overruling experience.)
