When I press the start button nothing. Everything was fine a day ago. I found this plastic pieces under the pedals. Does anyone know where this come from. I check everything, fuses, battery, everything is fine. The dash lights up as normal. It is just nothing when I press the Start button.

 

Clutch switch?

 

Clutch interlock switch. You can temp bypass switch with a paperclip to be able to start it.

Replace plastic pad when you can.

 

I found the clutch plastic piece on the mat this morning, it looks white. I'm still not sure where that black spacer in the in the picture above comes from. Thanks guys!

 

I believe the part is identical to Honda manual cars but has a different part number for the S2000. If it shows unavailable, ask a dealer to see if they have the one that matches for another Honda Car.
