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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

POST 1 / ORIGINAL POSTEROriginal post

Good morning everyone, I apologize in advance for my bad English I own a 2007 Porsche 997 turbo in Italy. Yesterday it worked perfectly, today it doesn't turn on anymore! Car won't start (Crank No Start) new and charged battery, always on mains maintainer the starter motor runs perfectly disconnected and reconnected the battery after a couple of hours (in the hope that there were some errors to be reset) Starting test also done with second keys (without success) fuel pumps work perfectly all fuses and relays are ok! (both the front ones and those behind the seats) the continuous machine does not start! the starter motor turns but no combustion occurs when I try to start it there is a strong smell of petrol do you have any advice for me? Thank you

POST 2Original post

Sounds like no spark. Check for spark, maybe Flywheel position sensor quit? All fuses good?

POST 3Original post

Not sure if it is the same on the 997, but I replaced my Battery Cable to the starter and all of my starting issues went away. The cable was totally corroded (which I could only tell AFTER I took it out). I also replaced the starter but 99% sure it was the cable. Post where I worked through the issue: https://forums.pelicanparts.com/porsche-996-997-991-forum/747417-1999-996-wont-start-when-hot-cranks-2.html#post11657671 Part I replaced: https://www.pelicanparts.com/More_Info/99660701901.htm?pn=996-607-019-01-M100&bc=c&q=starter%20wire
