No start 2012 Defender

Hello Mate,
I have a Land Rover Defender 2012 model (Puma). I was told that the injector needs replacement.
The car cranks but doesn't start. A times, it does a short crank.
Please, any idea about this particular problem? The car is less than 30,000km yet I was told to change the injectors.
Thanks.

Where are you located @KZ205 ?
Who told you the injectors need replacing ?

How the hell would they know injectors needed changing if it was not running at all ?
Sounds more like a battery issue, more so if original from 2012.
A rough location can be useful, there may be another forum member nearby.
