Why has my 2014 Holden Colorado suddenly stopped working?

Asked by Alastair

My 2014 Holden Colorado just died. It was sudden, it didn't bog down’ just stopped, so it's an electrical issue. What would be most likely causes?

Modern common-rail diesel engines with their sophisticated, multi-pump fuel systems and high-pressure injectors can stop in their tracks for any number of reasons, not all of them electrical. You could start by checking the battery and the charge-rate from the alternator (if the engine will restart). But you also really need to be checking the fuel system and the obvious stuff such as a dud ignition barrel that’s shutting everything down. A simple fuse or relay that controls the fuel pump system could have failed, too, with similar results.

The absolute best advice is to have the vehicle electronically scanned at a workshop with this type of diagnostic gear. By having the vehicle tell you what’s wrong with it, you’ll save a whole lot of time and money replacing random bits and pieces, hoping that you’ve identified the culprit.
