Injector service life depends heavily on fuel cleanliness, correct filtration and proper installation. Replace fuel filters on time, drain water from the fuel system and avoid contaminated diesel. If metal debris is found, inspect the pump, rail, lines and return circuit before fitting a replacement. Professional diagnosis should include fuel pressure testing, injector return testing, cylinder cut-out testing and ECM fault code reading.
