Intermittent Start Problem - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Just started having the exact symptoms and issue, came across this thread when searching the forum... all electrical working, but turn the key and there is no crank, no response. Remove the key and repeat a few times, it eventually fires right up. Good to know I'm not the only one... Will check relay 7.

This is really frustrating, I have been trying to nail this down and have changed the switch and bypass...now I guess its time to try the relay or dig into the pocket!!!

DG, this is a very old tread..

But, could you please provide more details on the symptoms and what have you done troubleshooting wise?

My problem turned out to be a weak "positive" ground in the engine compartment. It was rusty, and if I wiggled the cable and turned the key the engine would start. Disconnect the battery. It is located in a black plastic box next to the power steering reservoir. Use a screw driver to pop the box open and a 14 mm socket to remove and clean the nut.

I had the same problem ..i replaced the entire cable the new cables are upgraded more thicker...that cable looks like a " y " one goes connects to the little black box in the engine compartment and the other end one goes on the starter and one on the alternator....when they go bad they heat up and wont produce any eletricity to the starter or alternator
