Strange cut out

[MoreSteam]

Hi,

I had a strange one today where the engine cut out and I coasted to the side of the road.

When I tried to start it again it would fire and rev up to about 3500rpm with my foot off the pedal and cut out again. I tried this about 5 times and then left it for a couple of minutes (while some irrate drivers tried to get around the roundabout I was partially blocking).

I then tried it again and all was OK . I looked at the fault code unit, but nothing was displayed.

Any ideas?

Cheers D

yes ................. its a TVR.. they do that sometimes Sir..........:

Possible fuel starvation, check relays, fuel pump for possible fault..have had a similar fault due to fuel tank imploding....basically the tank was unable to breath, You would normally get a loud donk from behind you though.

I recently changed the gasket on my fuel cap as it was falling to bits. The new one will be making a good seal. I'll try to cut a bit out of it to see if this helps.

From what I've read I wouldn't advise doing that. I think it's supposed to be a closed system, with the tank being vented via the carbon canister. Doing what you're proposing may work, but it won't be fixing the problem.

I have same problem, very intermittent and never happens when garage has it!!!! After it cuts out you need to wait 20-30secs then it runs fine, before that time it fires and dies. I am convinced it is a fuel blockage but pump primes and stops so must be getting to the pump ok, my thoughts keep pointing towards the carbon canister and the valve that opens the loop but without changing bits all the time it is a b*stard to diagnose. (all relays changed)

Run it with the fuel filler cap half a turn loose. That will prevent any vacuum forming in the tank. If you still get the problem, you know that wasn't the cause.

I had this and it was the ignition amp on it's way out....

Sounds pretty much the same. Does yours rev quite high when you try to restart?
