OK? a glow plug cannot break?
Anyway, that is not how reliability assessments are made.
That would be: parts present combined with their respective mean faillure rate.
Personally, I think glowplugs in general show a significantly higher faillure rate than the combined chain of battery, sensor, electronics and sparkplug.
