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.

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.

14 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.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Porsche Cayman GTS 4.0 2023 Does anyone know if there is a fuse that can be pulled out that will stop the car from being started? I have tried pulling the one for the Fuel Pump but the car still starts with that 20 Amp fuse out. Thanks

POST 3Original post

Have you tried removing the fuel pump relay (not the fuse)?

POST 5Original post

Agree with TDT. Why would you want to do it? I sort of get it if you're going on holiday for an extended period of time (months) but in any case if someone wants it they'll take it at all costs.

POST 6Original post

Just fit a battery terminal switch (I have had to do this on previous classics where there was a parasitic charge) OR fit a liteblox battery this has a coded cut off via bluetooth. Kills all supply cannot be turned on without the code.

You have just made it sound like you have a body in the boot.

Thanks PJT This is PH, full of t ts that will give you advice and an opinion you didn't ask for. Now, along comes a div to say "case in point" or some other predictable s te.

POST 10Original post

Many years ago a car alarm installer told me the simplest way to stop a car being started was to install a simple hidden switch in the negative feed to the fuel pump.

POST 11Original post

Would doing that enable you to build oil pressure before fuelling the engine ? And if so would the car then register an ECU fault ??

POST 12Original post

My friend, after his F30 335d got stolen, has fitted a number of theft countermeasures on his Volvo. Rather than killing a fuel pump or something, he has a hidden switch attached to the fuse for the start/stop button. Even if the key was relayed, (which it won't be in a faraday cage, and kill switch installed on it!) the thief would be in the car and unable to start it as the button is completely dead. They would be stuck forever trying to figure it out. Very simple and effective if you ask me.

My Cayman is ignition key operated. Phil.
