hissing fuel cap

[R&J]

Hi Guys,
this afternoon driving along, roof off in my own little TVR world and my chimaera stopped running whilst travelling @ 60-70mph, I pulled over tried to restart and it was cranking but no life, (as if no spark or no fuel), waited 5 mins tried again and it gradually spluttered to life and has been fine since. During the afternoon I did notice a hissing noise from the fuel cap, I released the pressure. Is it probable that the tank had a vacuum and stopped the fuel. Any help will be greatly appreciated.

Could it be that something may have knocked the breather pipe and caused it to kink? What about something blocking the end?

I'm no mechanic and I have never had this problem before. But surely the breather pipe is just a thick piece of hose?

No.... Not necessarily.

Some hissing is normal. and doesn't indicate that anything is wrong. The two may not be connected at all and that simply waiting 5 minutes has cooled the car down so that whatever it was that was causing the problem has corrected itself.

If it is clocked breather vent, then the pipe is either blocked or the purge tank is full or the purge valve is faulty. I wouldn't do anything as yet. See if it happens again. Getting to these components is not nice at the best of times and it can be easy to get onto a wild goose chase.

Thanks Steve, I'll wait and if it reoccurs I hope that it happens in a convenient place, think I i'll avoid town centres for a while.
