2002 Porsche 911 Carrera has stalling/dying issues

[FL911]

I am really hoping someone can help me out with this issue.  I have an 02 Porche 911 Carrera with 101,151 on the clock, manual trans.

I decided it was time to update the IMS bearing and the RMS seal was beginning to leak so I wanted to change that as well because I am very picky about my cars.........1. not leaking oil and 2. being very dependable and well maintained!

So, after I finish this work that took me about a month because I could only work on it on the weekends, I get it all buttoned back up and I am excited because I am an extreme DIY'er and I felt like I had accomplished something and saved myself quite a bit of money in doing so.  Anyway, I am set for my first test drive, everything was triple checked (timing, fluids, etc.) and so I am off.  I only went for a short 5 mile drive and on my way back while at an intersection, my car suddenly dies!  Like I had just turned off the key.  Try to restart and nothing. Get a push into a parking lot, get out and check under the hood and all looks normal.  About 2 minutes go by and I try to restart it again, and it starts right up.  Get back home and go over everything.  All is fine.  Go out about 10 minutes later and it does this same thing to me 2 times again!

 

 After a few days of no sleep and pondering on what in the world is going on and after reading that since the battery was disconnected for so long that the DME may need to relearn or reset itself......  I decide to take another short drive, this time I am on a small local highway and it dies all of the sudden at 55 mph.

 

I replaced the Camshaft Position Sensor thinking this was the problem.  Drive the car for about 40 minutes with no issues and I am home free....right?  Well, later that day I decide to take my daughter to softball practice in the 911 and needless to say it died on us about 7 miles from home but this time it will not restart!  I had to trailer it home and now no one including me will drive the car unless/until it is fixed!!!

 

While it was still on my trailer, one day later, I get home from work and decide to try to start it.  It starts right up and runs fine.  But I will not drive it until I fix this issue. :help:  

 

Any advice would be great.  Against my better judgement, I am at a point where I am seriously thinking about taking it to a local Porsche shop to have them look at it.  Otherwise, I will just be throwing money at parts that may not be bad....like the Cam Sensor....that was $140 and was apparently not the problem.

 

Thank you,

My car is having issues starting after hot. Its never not started though, and I believe my issue is this; http://www.renntech.org/forums/topic/47219-hard-start-after-refuelling/

May be worth a read....

It sounds like a bad ignition switch? Maybe worthwhile just to change it out since it's cheap. It's unlikely you can fix something like this by just throwing parts at it since there are many things that can go wrong. If you plan to troubleshoot further, I would suggest you get Durametric to see if there are any pending codes stored and cam deviations.

I stewed and pondered on this for 3 weeks and decided I could figure this out.  Ended up being the Fuel Pump Relay..............a $9 part!!

 

Thanks for the input.

Glad you found the problem. I guess you threw off a few of us when you said "Try to restart and nothing". I read that as car didn't even try to crank.

It would restart on occasion but other times turn over without starting.  I am guessing at that time the relay was on the verge.

Well anyway I am back driving the car and enjoying it.

 

Thanks again.
