996 Starting Issue

Maybe they took it for a drive and swapped out some parts before returning it!

I apologize for asking a 911 question on a 986 forum. I didn't mean to reopen any healing wounds. Yes, there are other 911 specific forums and I had done a lot of reading of threads on them before asking my question here. But I'm not a member on any of those forums and this is my 1st 911. I split time between here and P-9 and a small bit of time on Quattroworld, so I didn't want to join another forum. I recall several recent "my Boxster won't start" threads here and most pointed to the CPS. I don't recall if any responded back that that fixed the issue. Since my issue didn't seem to point to the CPS, I was hoping someone would have other suggestions. Short story long, my question may not have been appropriate here but I trust the brain trust of this forum.

I rode with the guy for the long test drive but he wanted to take wifey on a short drive in the neighborhood to see if she liked the car. I forgot it has a 'back seat' and let them go by themselves. So they had opportunity. When they got back, we went thru all the buttons and the one that stumped me (it's been 9 yrs since I had my 01S) was the button with the key on the upper right horseshoe. We pushed it back and forth and I wondered later if it immobilized the engine. Have since found out it's the central locking button.

"I appreciate everyone's input."
You are welcome.It is an M96 with a potential CPS problem. So all that is suggested is 100% relevant to the 986 Boxster also.
Back to the CPS. The heat related failure mode can be simulated. The procedure requires you remove the CPS , connect a DMM and watch the Ohms change when you heat it with a powerful hairdryer.
JFP an expert(unlike me!) suggests specifically( and I know you may have done this part of the diagnostics already):
"Remove the CPS sensor connector, connect your Multimeter to pin #1 and pin#2, at 68F it should read 0.8-1.0K ohms; then connect the multimeter to pin #1 and pin #3 and it should read infinite ohms; if it does not read correctly in either range, can the sensor and replace it. "

At least it is a simple job with a reasonably priced part :-). Good Luck and let us know what the fix was.It may be an omen - keep the car !

Thanks Gelbster.

I did the ohm test with a room temp CPS and got those figures. Didn't try the test with a hot CPS. My brother spoke to noted Porsche mechanic Karl in KC and Karl's suggestion was to replace the CPS. Just did some Internet searching and found one for $112 + $10 shipping, so a new one is on its way.
