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.

Leading evidence: 'Use car' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use car' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

If I make a short journey (a mile or so) and park up, I seem to have occational problems re-starting the engine if I return within 10 minutes or so. It always fires up after about 4 attempts (and a few deep breaths) though.
Other than that, it runs just fine, and always starts from cold.
Anyone else experiencing this with their early 996s?
Thanks, Jay

No problems like this with mine (although its a 2001). When you say problems re-starting is the car turning over or is it like the immoboliser is engaged ie nothing happens at all?

Ummm - sounds like you need to do a straight swap for an '87 cabriolet - fortunately I know a chap who has one....
but seriously - sounds like the engine management systems are being fooled by the just-off-cold engine - what's the mileage ?

You know, if I were allowed 2 911s (its been made perfectly clear that I'm not!), I would also have a late 3.2. The iconic 911 shape.
Current mileage is around 32K.

A friend of mine used to have a similar problem with a Lotus Esprit V8. It was new at the time and everytime he turned it off he would have to wait to restart it. I once pulled up on a yellow line, turned the car off, it wouldn't restart. It was clear that it wouldn't start with the engine just turning over and a traffic warden wrote me out a ticket while i was trying to start it and on the phone to Lotus!! :evil:
I think it was something to do with the ECU and they had to replace it.
I got out of the ticket

Sounds like 'monday morning syndrome' to me.... so called cos cars that were started up, driven out of the garage then washed and put back in on Sunday didn't start on monday.
Manifests itself on cars that are driven a v short distance from cold, then switched off.
Basically, the lambda sensors in the exhaust (?) cause the engine to overfuel on start up the second time, so it floods...
To avoid it, make sure there is a reasonable temp showing on the temp gauge before switching off.

RobertB - am I also right in thinking that in this situation, holding the revs at say, 2-3000 for a second or two and turning off the engine whilst still revving, purges the cylinders ?

Mine (1998 C2) does exactly the same thing. Although I've no idea what it is, it doesn't seem to cause a problem. I think it has something to do with the engine management as the oil time is always at 8 or 9 minutes when the issue occurs.
I am due to get the car serviced in the next two weeks so I'll ask the guys what they think and let you know.

Thanks Matt.
As you say it doesn't seem to be a major problem. Though it does worry me that one day I'll have to be towed away from outside my kid's school
Let us know how you get on.

Don't know... I try to make sure there is some meaningful heat showing on the temp gauge before switching off.
The RAC man who came round to start my XK8 one morning a while ago that had this prob did the following; removed fuel injection fuse then asked me to crank the engine for a few secs until you could hear it trying to fire. This was to avoid unburnt fuel getting in the cats and damaging them.
Then he put the fuse back in, and asked me to crank the engine with the accelerator flat out- after a little while the engine will start to fire, and of course you have to be careful to take some of the throttle off when the engine fires if you don't like revving cold engines... but don't let it stall or you're back to square one.

Had exactly the same problem with mine as well, 8 or 9 minutes on the oil gauge, engine turning over fine, just not starting....I think its deffo to do with a short journey...this happened when I drove to the pub at lunch, about a 3 minute drive, came out after lunch, wouldn't start....waited 10 mins and it started fine...I vote for engine management logic gremlins....
