Giving Up.... :(

What did you find when you checked the starter, did it turn the car over when you jumpered it?

You need to check and see if you have B+ to the starter, if so make sure you are getting B+ to the bendix when the ign switch is engaged, if you do then you simply need a new starter. If not you have a deeper issue.

I had the EXACT same symptoms on my Ford Ranger. After several hours of trying to diagnose the problem on my own, I gave up and took the vehicle to the dealership. It turned out that the positive battery cable went bad. It was providing enough power to run the accessories and headlights, but not enough to start the truck. I'm not sure if this would cause the same symptoms on a Boxster, but have you check out all the cables to be sure?

Same here with the wife's Old minivan, that problem plagued us for 3 months, it was intermittant and stranded her and the kids a few times.

The starter spun well when i checked the starter by jumpering. The engine cranked when I checked starter and solenoid.

Thus, I feel like I am running out of things to check. At this point I'm thinking it must be an immobilizer issue. Thoughts?

(now that I have the throttle body off, any maintainence you recommend while it's out? Seems to be a bit of oil/dirt in there. AOS problem?)
