Start problem

[egx]

Hi guys,

i picked up my new to me boxster 1999 2.5L

Everything works fine, although sometimes i turn the key and electronics go off but no ignition. it's not the battery because i just lock, clutch in clutch out lock in unlock and boom everything works fine. doesnt seem to be consistent.

what can it be? ignition switch? old keys? clutch switch?

thanks!
