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.

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

POST 1 / ORIGINAL POSTEROriginal post

I’m hoping someone can help. I have an 2003 Boxster S. I recently changed the engine over went in without issue but when it comes to starting it won’t fire. Turns over sounds healthy but just keeps spinning and won’t fire has anyone got any suggestions as to what the issue may be.

POST 2 / ORIGINAL POSTEROriginal post

I've recently swapped engine and gearbox on my 2003 986 S. All fitted nice and neat no major problems with the swap. My problem is it wont start. It turns over but wont fire. Current situation is its on a ramp wheels off roof down. I've tried locking and unlocking and all the what my mechanic thinks is the obvious stuff but just wont fire up. Have you experts any idea of what to try next

Are you getting fuel? Are you getting spark?

POST 4Original post

Quotes source post: 667777

My simple answer: Go back, as many times as it takes, and figure out what you failed to connect, or connect properly. Do you see any codes that have been thrown? That might help focus your efforts.

POST 5Original post

CPS signal?

Turns over sounds healthy but just keeps spinning and won’t fire has anyone got any suggestions as to what the issue may be.[/Q First thing to do is determine if the issue is due to no spark or no fuel or both? Get a can of starting fluid spray some into the intake then crank the motor over. If it fires or sputters then that will tell you that your getting spark but not getting fuel. Very simple test that will give you a direction to go.

POST 7Original post

Nallace - I’ve merged your threads. You don’t need to make multiple inquiries for the same issue.

POST 8 / ORIGINAL POSTEROriginal post

UPDATE My man on the spanner’s seems to think it’s the immobiliser as it’s not sparking. Can I bypass the immobiliser

POST 9Original post

No, without the correct signal from the immobilizer, the DME will not allow the car to run.
