My 01 seems to have developed a starting problem. It seems to happen after it has sat for a couple of days. This morning it took eight or nine tries to get it to fire. It just turns over with no hint of wanting to start. Once it finally starts, it runs fine and starts immediately after that. I think it is more related to sitting than the near freezing tempuratures we've been having lately. Anyone have any thoughts on the problem/fix?

 

If you're still with the original battery, might be a low battery (unlikely for a Porsche OEM battery to last 6 years).

 

If its cranking and turning over doubt the battery, although you will need one if this keeps up, sounds more like a fuel pump issue??
Also probably time for a plug upgrade.
