boxster starting problem
 

Turn ignition key and all dash warning lamps work. There is a fuuny noise from dash and electric windows judder slightly.

Battery checks out and is charged. Have triied to start in park and neutral but no joy. Car started fine 4 hours earlier.

HELP

I had something similar and it turned out to be a failing clutch switch. however, since you mention putting it in "park" and "neutral," I assume you have a tip??

otherwise, strange electrical can sometimes be a failing ignition switch. have you ever replaced yours?

are you sure the battery is ok (I know you said it "checked out," but I'm not sure how you tested it).
