Leading evidence: 'nut behind the wheel' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'nut behind the wheel' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check fuel filter first' (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.

I suggest checking the halogen fluid levels and replacing the prop wash.

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.

My 2004 carrera 4s stalled behind a red light. Can anyone tell me what might be wrong with it? Gas tank was full and it stalled without making any sounds. BTW, it has 77K on it and is manual.
Well, based on your description this is very easy to diagnose. Since you said red light and no noises, and gas tank was full...I would say your muffler bearing failed. No other possibility here.
On the serious note, you need to provide a lot more information about the car's condition. Did you try to start it? Did it turn over? Was starter engaging? What was volt meter reading? Did you try to push start it? Did anything smell bad? Did any fluids leak? Is the car your daily driver or did you just take it out? Any deferred maintenance?
Gentlemen, this is a very serious question ... this 911 is STALLED, STALLED I say! At a red light no less! I suggest checking the halogen fluid levels and replacing the prop wash.
Tough crowd here.
More info needed as others said. Also you can guess by now that you need thick skin to hang out here sometimes.
Did it happen only once or are you still driving it? Was it towed to a mechanic or dealer? Was there any work done on it recently?
A otherwise uneventful stall and then a crank followed by no start is very suggestive of a fuel problem, either a bad relay or fuse or pump.
If the engine stalled and then there was no cranking this can be a bad ignition switch or possibly -- if a manual -- a bad clutch interlock switch.
Getting the car flat bedded to a qualified shop should have the cause diagnosed.
An engine just stalling could be a clogged fuel filter. That is a bit unlikely. You get clogged fuel filters usually in older cars that have gunk in their gas tanks. It is not impossible however. I would check the fuel filter first.
I assume it started up again, right? Another possibility is some kind of quirk in the engine electronics. These cars seem to be prone to all kinds of gremlins in their electronics. Your engine computer could have just shut it off for no reason.
Here is the $60 question, when it restarted did it run well at the proper temperature and oil pressure and with the expected amount of power? If so, then it has to be your fuel filter or some kind of electronic glitch. If it were something mechanical, it would have never started up and ran fine. Valves and fuel injectors and such just break. They don't generally take a moment off only to return to working properly. It is electronics that will lose connection or malfunction and then magically return to working normally.
Only 3 things keep an engine running, spark fuel and air (there's ECU variable too) If the fuel pump didn't quit, and world didn't run out of air, sounds like misfire at idle stalled the car.
Look for codes, check the plugs and coils. Has it stalled before? Assuming your sitting, car in neutral not moving at idle goin nowhere and bam dies?
Smells like troll in here. 1 post, "broken Porsche" topic, and the diagnostic evidence consists entirely of "it stalled" and "it has fuel"?
Don't cross that bridge, billy goat!
Actually, he made the same post in the
Reddit Porsche forum
yesterday before posting here - so I doubt it's a fake. He replied there a few times as well, give the guy a break!
Anyways, I have to agree with the fuel diagnosis as well. Judging from your questions over on reddit, I think you need a shop to plug it into the computer and scan the codes.
Good luck.
I'd also guess fuel pump from the limited info here - esp if it cranks. Not sure how easy it is on these cars to screw fuel pressure tester into injection rail - but you can rent those at auto parts store or just take it local indie to diagnose And replace . Not sure where pump is located in this car ( in most new cars it is in the gas tank itself) or the cost to replace ...
Eagle, wtf are you thinking? Your car has way too many miles on it for an 04. Its stalling because its trying to tell you "STOP DRIVING ME"! Please park the car in your garage and begin an immediate engine drop. Your a n00b here so we're assuming you didnt see the forum provided diagnostic flow chart to troubleshoot your issue. Please keep us posted.
OP, are you still waiting for the light to turn green?
You probably have a red light sensor installed. Once it turns green, you will be on your way. Patience, patience.
.
No, not the same. You will note that the guy on Reddit has a PROSCHE. Completely different car.
.
The more troubling question is why did he go to Reddit first? Does he really think that Reddit can explain the 95,000 modes of failure for the 996 "Prosche"?
