Car not starting

[vigor]

I put the key in the ignition, all electronics function properly, but car won't start.
It seems like it may be the clutch or a sensor at the clutch thats malfunctioning.
I hear a clicking noise whenever I step on clutch.
Checked fuses and they seem to be fine. It doesnt seem to be the key's codification since the electronics turn on and it opens the doors.

Anything else I should try?

BTW: this is a 99 boxster.
