Why has my 2014 Holden Barina stopped working?

There are literally hundreds of reasons for a modern car to simply refuse to start. However, there’s one way to perhaps tell if the starter motor is the problem or not: When you turn the key, does the engine crank over? If it does, regardless of whether it starts or not, then the starter motor would appear to be fine.

If the engine doesn’t crank, the starter motor might still be okay, but you might have a flat battery or an electrical problem. Even a problem with the automatic gear selector (in the switch that that prevents the engine being started in gear) can cause a no-crank situation even though the starter motor itself is fine.

A good mechanic should be able to run a few tests and figure out pretty quickly what’s going on and what’s wrong. They will check the fuel system, ignition system and, of course, the starting system, and work it out from there.
