172 cup won’t start

[Jamescup]

Hi, went to start my car after filling up and the ignition comes on as usual and the dash lights go off as usual, but the final turn to start the car nothing happens. It sounds like theres clicks coming from the relays/fuses. Ended up having to jumpstart it and drove fine.

Power to the starter motor so thought that was jammed and changed it for a new one. Still the exact same issue. So stuck on what the issue is, does anyone have any ideas or has it happened to anyone else?

If a jump sorted it, it has to be battery/power related surely?

The battery is fine, and there is power going to the starter motor. When you do the final turn, a relay switches like its ready to go but just nothing happens at all 🤷‍♂️

Cleaned the fuse box as there were dirty and full of grime, replaced earth strap and has fixed the issue.
