He checked the above connector and he says that it is not short-circuiting there.

I checked the E6 fuse and it was blown, so I replaced it with a new one.

Suggestion
Of course I don't know what your mech did as diagnosis - but I'd certainly be getting it to a dealership for a second opinion, but only after I'd spent a few hours on Sunday tracing that cable loom from the cellphone connector back through the car to the fuse-box - and checking for broken/worn insulation.

He checked the fuel tank valve(s) and he says that a valve actually did go bad and that valve is inside the tank, which itself is sealed and thus a new fuel tank is needed and quoted me app.

I will check with my mechanic on Monday morning and if he cannot rectify it, I will take to the car to the Porsche dealership to at least make sure that the car is checked with the proper Porsche tester.

I have found the Porsche shop I will taking the car to, but I have been very busy and I'm not doing a lot of mileage anyway, so I'm still running on the gas I filled about 2 weeks ago.
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.

So now that I bought myself some time, I will look for a specialist to get it fixed.
Hello guys!
I am having a problem filling up my gas tank and I was hoping that someone might know what it is.
The last time I tried to fill up my gas tank, it filled up to about half full and then it spilled some gas out - before the pump could stop automatically.
I didn't pay much attention to it then, but today that I tried to fill it up again, it only took about half a gallon and it spilled some gas right back out.
I tried filling it up slowly, but still no success.
I am taking it to my mechanic tomorrow morning, but he says that he doesn't know what it might be.
Has anyone had this problem before or does anybody have a clue what the problem might be and how much a fix would cost?
Thanks!!
George
Thakn you guys!!
I checked the E6 fuse and it was blown, so I replaced it with a new one.
However as soon as I tried to fill up again, it got blown and the tank didn't fuel.
Also, the CEL is not lit.
Any ideas?
Thanks again!!
By the way, although probably irrelevant, it might not be after all if there is an electrical problem.
Last week my ipod would charge normally at times, while at other times it would not charge (I believe it is powered by the stereo), although it would play fine.
At this time, it powers fine.
So I thought that the problem might be in the electrics.
Shorted wiring loom is your problem - I think it's shorting out, and from memory it's around the steering column area
I'll see if I can find the exact info
E6 is the same fuse as the cell phone hook up, and it's likely to be the cell phone connector that's shorting to ground taking out the fuse.
First take off the panel (pops off) to the right of the accelerator and tape the end of the cell phone wiring harness that's in there.
It is likely dangling in your lower center dash console area (you can also pull a storage binnacle to access)
Starting in 2003 Porsche put tape on the connector so it would not short out.
Thank you!
I also found an old related link:
https://rennlist.com/forums/996-foru...ease-help.html
However I couldn't really understand either instructions.
How will I identify the cell phone wiring harness?
Could you give me a little more detailed and clear instructions please?
I tried to remove the panels around the center console, but I could not get access to any wires.
It is all plastic or carpet and I was afraid to pull the carpet too hard in order not to break or tear anything.
No problem - here's the side panels being removed:
Then you can grab and pull out the storage cubby bin(s). First do the top one, then the bottom. If you have a tape or CD holder, the process is the same.
You should now be able to reach in and find the cellphone power plug which will be loose and not connected to anything (unless your ipod connection used it...?)
Tape up the open pins on the connector, so they can't short to ground on any piece of the car.
Hopefully that should fix it.
if the fuse still blows, then the wiring from that cellphone power plug has chaffed through somewhere near the airbag control module usually, and you'll need to remove the carpet to check the wiring loom as it traces back through the car towards the fuse box
You do this by grasping the rear edge and pulling outward, away from the center console.
Trace the colored wires, and find where the cable insulation has been broken - tape up and repair as required.
You can see the wiring snaking around the center console frame in this side shot. (Ignore the red circles, that's for complete removal of the console sub chassis)
Let us know how you get on
Thank you cdodkin!
I took the car to my mechanic today.
He checked the above connector and he says that it is not short-circuiting there.
He checked the fuel tank valve(s) and he says that a valve actually did go bad and that valve is inside the tank, which itself is sealed and thus a new fuel tank is needed and quoted me app. $2,000 for the tank including labor.
I checked (
http://www.trademotion.com/partlocat...e=29&model=911
Carrera&year=2002&graphicID=6932230&callout=9&catalogid=2&displayCatalog id=0) and I see various valves around the tank, so I am wondering if any one of those is the one that needs to be replaced.
Any advice please?
Thanks again guys!
My mechanic doesn't known the exact name of the valve, but he says that it is the valve that prevents fuel from spilling out in the case of a roll-over.
No, this is (unfortunately) not at a Porsche dealer although he does have experience with Porsche's.
I don't even want to think how much Porsche Beverly Hills would charge to repair by searching around...
All right, im having a mind fart im not sure of thats the new or old sytle,
First thing replace the fuse and acuate to door in the fuel neck with your finger. Do you here the valve opening. If it is not opening you could have a bad magnetic switch that isnt opening the valve.
The valve should be under the battery tray (remove the battery and the tray) towards the drivers side of the car about 2 inches from the fuel pump ring. It is wrapped in thick styro foam. You should be able to remove the hoses from this valve, you will have to cut the clamps . At this point the vechile should take fuel. If it does you have found your problem.
If I cut out this valve, will it be safe to move around the car until I get it replaced?
What if the car still doesn't take fuel?
Do you think that the replacing the whole fuel tank is not necessary?
Also, can anyone suggest a good, reliable and reasonably (cheap) priced mechanic in West Los Angeles for the task?
Thank you again!!
I would not recomend changing a fuel tank unless it has physcal damage to it. If you need to add fuel to the car, pull the fuel pump top off and pour it to the tank from there. then you can reinstalll the pump top and drive the car. you dont want to move the car around with the fuel tank open or the hoses off the valve. I would put money on the valve on top of the tank there.
Thank you very much!
I will check with my mechanic on Monday morning and if he cannot rectify it, I will take to the car to the Porsche dealership to at least make sure that the car is checked with the proper Porsche tester.
Do you know if the Porsche Tester would be able to pinpoint the problem to a specific valve?
No CEL is lit.
no the tester is no help in diagnosis this, but you do need a througouh understanding of the system, that you may not find with someone who has not been through this before
Thank you 99firehawk!!
Do you by any chance have any pictures of what I should be looking for?
Fuel pump top and the valve wrapped in foram that is?
My mechanic told me that the gas tank is sealed and it cannot be opened or accessed, which is not true from what I understand, so I am wondering if he thinks that that foam is a seal and cannot be torn apart.
Thanks again for all your (and others') help!!
Just my 2 cents: It seems this mechanic might not be that knowledgeable about Porsches. I would take it to a good Porsche indy or a Porsche dealer. Best of luck with this.
I'm also questioning the diagnosis - The fact that the circuit is hard shorted to ground (you note that the E6 fuse blows instantly with a spark) would suggest an electrical fault.
I'm not convinced a valve failure would do this, I'd expect it to fail open circuit, not short circuit.
Of course I don't know what your mech did as diagnosis - but I'd certainly be getting it to a dealership for a second opinion, but only after I'd spent a few hours on Sunday tracing that cable loom from the cellphone connector back through the car to the fuse-box - and checking for broken/worn insulation.
Just my 2c
Thank you guys!
I will give it another try with him tomorrow and then I'll look for another Porsche specialist.
He does work on Porsche's. He is not a Porsche-only shop though and I guess he doesn't have that much experience.
Could anyone confirm that the fuel tank actually does not have any valve installed inside it, which cannot be replaced indepentently from the tank (or not)?
Also, would anyone have in mind any illustrated instructions of the fuel tank valve replacement?
Thanks again!!
Agreed! Why ask for help if you are going to ignore the advice given? A waste of time and effort for those (especially Firehawk) who decided to help. Newbies!!!
To the OP: In case you don't know it, 99firehawk is extremely knowledgable about Porsches.
Thank you again guys!!
Right now the car has very little fuel in it (app. 20 miles range), so I have to know where else to take it and I don't yet. So this adds to the problem of taking it to another shop.
First decide on which Porsche EXPERT you intend on bringing your car to have it repaired. Then, if you can't get any more fuel into it, have it towed. It's better than making your decision based on the proximity of a repair shop. And a LOT cheaper than paying for a new gas tank you probably don't need.
I found a way to put a gas into the car today (by holding the gas nozzle upside down and pouring little by little) and took the car from that mechanic.
So now that I bought myself some time, I will look for a specialist to get it fixed.
Thanks for all your help guys!!
Not yet.
I have found the Porsche shop I will taking the car to, but I have been very busy and I'm not doing a lot of mileage anyway, so I'm still running on the gas I filled about 2 weeks ago.
I will keep you posted though!
Nothing new yet. I have been very busy lately to stay a couple days car-less and thus I have been making do by filling the tank slowly with the inverted gas-nozzle trick.
Geez, don't rush the guy. It hasn't even been 2 MONTHS since he first posted.
Really though, it kind of makes you wonder why he wasted his time, not to mention the time of those who replied to him, asking for advice.
Hello again!
Finally some news. The problem was solved, which turned out to have been caused by a failed ORVR valve.
Btw the issue was rectified by Callas Rennsport. Kudos to Tony!!
Did you read the thread posts to which you added your request for help?
A quick glance I gather the problem can be a fuse or some hose that has come undone.
In the case of the fuse you can replace this with a similar fuse but if the fuse blows again there is a short. IIRC the fuse also protects some other circuit though I don't recall which one off hand. I think it is something related to a phone which in my reference is E6. If this fuse proves to be bad then you would have to trouble shoot that circuit.
For the hose I think this is accessible but you have to remove the right front wheel/tire and the wheel well liner. There are a bunch of hoses -- fuel tank venting/vapor recovery system related -- under there and I'm not sure which hose is suspect. From what I recall reading this is generally something the owner has addressed at the dealer or an indy shop.
This is a source reference. Confirm exact model applicability in the original material.
