Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that report identifying a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Just wondering before I start my checks on this problem , starts and runs very nice and smooth ,shut off after driving for 1/2 hour or hour let sit for 5 min and will turn over fine but no start at times , wait 1/2 hour to a hour fires up fine.never stalls out while driving just a start up issue. battery tested fine , starter seems a little bit slow,but same cold or hot . 2000 911 C4 thanks for any ideas,will post findings and cure.

POST 2Original post

My car did the same thing. I took it to Porsche 3 times and they could not duplicate the problem. I ended up driving it there when the car was cooking hot and put the service writer in the drivers seat and had him try and start it and the starter barely turned.... bingo new started, covered under my warranty.
