Diesel injectors fail for two main reasons: the mechanical integrity of the injector and the quality of the fuel running through the injector.
Like all vehicle parts, diesel injectors can become weak over time. Even though they are electronic, sometimes the mechanical components may become worn, cease to function effectively and even fail. An engine scan will generally pinpoint the problem cylinder.
