Aracerx:

Have you read the whole thread? It's the crankshaft position sensor!! Good luck!

Oh the shop replace it for me. I figured it would cost me more in time so I went ahead with the shop. They only charge me 1.5 hrs. Very good shop here in Tulsa ok. Rennsport is the name. I would definitely recommend this shop.

...Finally my car is back home! I'm happy to report that it was the CRANKSHAFT POSITION SENSOR!!!

As for the location of the sensor, I don't really know where it is. A few posts back, one of the guys said it was on the right hand side, & you have to take the tire off. I wasn't sure if he was talking about a 996 or a boxster. You might have to search or post another question on the location. People on here have been very helpful. I have alldata but it doesn't really tell me where. If I find out, I'll let you know. Good luck!

BTW, the part should get in today. I don't know they'll have time to get it done. If not, it'll be on Monday...

...ok, it's exactly problem as mine then. Have you had any liquid spilled inside of the car recently?

So far I have replaced the fuel pump & fuel pump relay with no luck. The shop have swapped out the oil temp sensor to see, but nothing changes.

They're getting the CPS & swapping it out Friday hopefully. I hope that works. I'll let you know ASAP.

I hate doing this but I've exhausted all my options as well. Let me know what you have tried so far.

Btw they said it could be the actual DME...

Omarcoolguy:

what kind of Porsche do you have? Can you describe your car problem? Does it shut itself off instantly when it's hot? Can you restart right away?

Thx

Well, finally got a call from the shop today, & they gave up too! They told me they have exhausted all options. I went ahead & asked them to change out the cranshaft position sensor. We'll see...

...nope! No words yet...

M, I'm glad you got yours fixed! I just talked to my shop this morning, & they still haven't found anything. I did suggest the crankshaft position sensor, but they rejected that idea immediately! We'll see...

Thanks for the update.

Michial, please update your progress if you get it fixed before me. I've given up & took it in. It has been in the shop for 2 days, & they haven't figured it out either...

Thank you! Yea, I've read a few post that said it was under the seat. I knew somebody would know. Awesome forum!

Cheers,

Does anyone know the location of the DME on a 996 cab? Alldata said it's behind the rear seat, but I don't think I can get behind the rear seat on a cabrio. Please let me know...

Best regards,

Once again, I really appreciate all the replies. The info is defintely valuable! After reading non-stop in the last few days, now I'm thinking my car is NOT really overheating. I'm narrowing down to "some" sensor such as crankshaft position sensor, engine speed sensor, fuel injection pressure sensor causes the NO START condition. My questions now are:

1) why would a broken relay, module or a sensor be okay again after the car cools down again?

2) would a bad sensor trigger a fault code?

3) right after the car stalls, can I take out certain sensor & test it?

4) Is it true that if the Fuel injection pressure sensor fails, I should see fuel when I pull of the vacuum hose that attaches to the sensor?

I think I'm getting somewhere! Hopefully :P

best regards,

Maurice: thanks for the suggestion. I've read that thread a few times, & I don't think I have the same issue. Mine pretty much runs normal until it gets to 200f & stalls out, consistently every time.

Btw, it seems like an overheating problem that I'm having but no warning light at all before it stalls out. I've actually seen my temp gauge up that high before many time.

More research...

Thanks again.

Wvicary:

do you know what controls the no start condition? After it stalls, I tried to unlug the battery for 10min to reset. It still wouldn't let me start the car! Also, what would the engine speed sensor tell me? I hope I ask the right question.

Best regards,

I'm sure nobody wants to take it to the shop if they can help it. In my case, I'm afraid I might be spending more $$ going in circle than taking it to the shop. The crazy thing about it is, the car still runs perfectly normal. No sound, no glitch, no code, no smoke, anything!! When it get to about 200 F, it will shut down instantly. I wouldn't be able to restart until about an hour later.

Sorry for going around & around explaining my situation :)

Please HELP!

Thank you Peter. I'll give it a try. It wouldn't hurt. After that, I'll have to give in and take it in to a shop :(

...Well, after reading info on other ppl that had similar issue, I replaced my fuel pump. Unfortunately, it didn't solve the problem.

I'm narrowing down to maybe the cooling fan switch or some sensor that triggers the cooling fans to come on. I've noticed that the cooling fans don't always come on when temp is over 190F. Also, the fans only come on for about 30 seconds max. I'm not sure if that's normal.

Here are the 3 things I'm looking at: Fan switch, thermostat, water pump. What do you think? Please chime in if you had a similar problem before. Still searching for answer....

Thanks a million..

...Let the car ran until it reaches around 96 deg. C, it stalled as usual. Replaced fuel pump relay, but it wouldn't restart. It seems like the engine has a cutoff point (coincidently) around 96 deg. C. It wouldn't restart usually around a few hours later. It feels like something really simple, yet I'm pulling my hair out. I'll try to get some info on how to check the fuel pressure to see whether the fuel pump is bad. I might be way out there but anyone thinks it's a thermostat issue?? It looks like the engine overheats & turns itself off everytime around the 96 deg Celcius.

Thanks for the suggestions as always...

Any code?

check the fuel pressure regulator,,,

No code at all. I'll check the regulator to see. Thanks

Hopefully someone had this same issue before. I have a '99 996 cabriolet. It has been running absolutely fine for the past 5 years. Never even had any problem. Did a 60k service 6 months ago (spark plugs, oil & transmission oil change, etc.) 2 weeks ago, I drove around for about 20 mins & parked. The car wouldn't start (cranks just fine but seems like not getting fuel) I waited for about 5 minutes & it starts again. Last week, while at a stop lights the car stalled. I notice the engine temp. is around 200F+. Now, if I let the car runs until temp. is over 200F, it would stall again

Anyone has any idea? Thank you in advance...

****I wanted to edit this so that the next person with the same problem doesn't have to read the whole thread to find out the solution. If you have the same issue, 99.9% sure it's the CRANKSHAFT POSITION SENSOR!! Good luck!

I desperately need the radio code for my car.

Becker 1

type 4462

serial#: X5024456

48/49

Thanks a million in advance!
