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.

Might be worth the expense to buy a new relay and have it handy and next time this happens just replace the relay.

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 1 / ORIGINAL POSTEROriginal post

I decided to take the GT3 out for play in the sunshine this morning but the car decided it didn't want to play... On first starting the engine ran for around 20 seconds then slowly died. It then just wouldn't fire. I gave up and called Porsche Assist who sent round an RAC man (apparently they don't work weekends) and, you guessed, it started first time, albeit with a seconds hesitation. It then ran fine and he couldn't find any fault codes. This is despite a message (while it wouldn't start) telling me to take it to a Porsche workshop and an orange engine warning light. At the time it seemed like a fuelling issue, but why would it sort itself out? Anyone come across this before?

POST 2Original post

Could be a fueling problem. The fuel pump ran then quit after few seconds. Won't work on immediate restart but after the car sits a while and the fuel pump cools down all is well again. This also applies to the fuel pump relay. Might be worth the expense to buy a new relay and have it handy and next time this happens just replace the relay. If the crankshaft position sensor quits the engine stops. The ECU shuts it down for it doesn't know where the pistons are and can't trigger the injectors or plugs. Since emissions are involved there is no CEL but the service light could be lit. Or just take the car in. There might be error codes logged that point to a sensor problem or give the tech a good idea of what happened.

Thanks Rockster. No problems starting it yesterday, think I'll take it in to the OPC.

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