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.

POST 1Original post

My 2000 Porsche Boxster S will start and run but after turning it off occasionally It just turns over and doesn't fire/start or even sputter. Hours later it will fire and start like there is nothing wrong. I do hear a howling sound while driving occasionally. Replaced fuel pump relay, same deal. Would bad fuel pump or pressure regulator explain symptom? __________________ This post was auto-generated based upon a question asked on our tech article page here:

POST 2Original post

Very common...99% sure you have a faulty charcoal canister purge valve (aka fuel regeneration valve?!). The purge valve is located in the engine compartment on the left side beneath the intake. Part number: 996-110-129-06-M100 - Casey

POST 3Original post

I would also look at the crank position sensor, which are well known to act up when warm, and then be fine when they cool off. When the CPS fails, the car often will not code, but won't start when warm because the DME does not see the engine turning and shuts off the fuel and ignition.

This is a source reference. Confirm exact model applicability in the original material.
