the crank position sensor would throw a code....mine did, about 2 wks ago...took it to the dealer and it was the driver's side...they replaced it...no code
Leading evidence: 'driver's side...they replaced it...no code' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'driver's side...they replaced it...no code' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check purge solenoid/valve' (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.

Suggestion · Original poster
As a last resort he changed the fuel relay hoping that would solve the problem.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Looking for some help for a very frustrating problem. I have a 1999 911 Carrera that drives great, but has developed a habit for not starting at the most inconvenient times. On at least three occasions I have driven the car then parked it for at least an hour and each time I came back and the car would't start. On one occasion the car started after I waited a couple of hours. The other two times I had to leave the car overnight before it started. I took it to my mechanic and he tried to driving it and then letting it sit,but of course it always started. As a last resort he changed the fuel relay hoping that would solve the problem. The next day I drove the car for three hours with a couple of stops. When I reached my destination I decided to wait a couple of hours before trying to start it�of course it didn't start. I let it sit overnight and I started on first crank the next day. It's driving me crazy because I'm afraid to turn the car off, fearing that it might not start again. Anyone experienced anything similar, or have any suggestions?
Sounds like a failing crankshaft position sensor.

Have you scanned the car with Durametric for any error codes?
Like Frank mentioned, the crank position sensor will fit the bill. However, without full diagnostic, it's difficult to say for sure. There are also other possibilities like fuel pump relay, ignition relay, etc. Being intermittent will make diagnostic quite difficult and time consuming for sure.
the crank position sensor would throw a code....mine did, about 2 wks ago...took it to the dealer and it was the driver's side...they replaced it...no code
How much of a bitch is this sensor to install yourself? I just ordered one.
I know you don't have to drop the tranny or engine but DO need to remove the passenger front wheel… assuming a lift is required as well…
Thanks,

Easier to get to if you go in from the left (driver's side in US) rear wheel. You will need to jack the car use jack stands you are going to be yanking on the thing some.

While the crankshaft position sensor is a high percentage diagnosis it can be the camshaft position sensors. If both are "bad" the engine will start but it takes 10 seconds.
Do you let the engine crank at least 10 seconds? Next time you encounter this engine not starting behavior you might try this. If the engine doesn't start no need to try it again. If it does this points to the camshaft position sensors.
Just a thought. To have both camshaft position sensors go bad concurrently and then start working again -- or there would be a CEL and error codes pointing to the camshaft sensor -- is a bit of a stretch.
Check the purge solenoid/valve near the throttle body. If stuck open, it will cause a hard start when the wngine us warm but if you keep cranking it for about 10 sec, it will fire up.
