1999 996 don't start

[rodwil47]

Nothing happens when attempting to start, no cranking, ignition switch replaced, the key was sticking in the start position, the car overheated max temp, and shut off while driving.

How can I check the starter? where is the starter relay?

I would try rotating the engine by hand, you may have seized it. These engines do no like being overheated...……..

Thanks for your reply, the problem ended up in the main/rear wiring harness.

My Key stopped working too..
It ended up being a cheap 11 dollar part in back of the ignition two tiny screws and clips right in cheap and easy fix.
