Default Warning!: no start after fill up
i have a 2006 S. It has always started quickly with no drama. Saturday I filled it with gas and it just cranked and cranked without starting until the battery died. I was fortunate to push it 10 feet and park it and caught Uber Home. I was thinking fuel pump and started researching. There was mention of crank position sensor. Kept reading and found a bunch of stories of my exact experience.

Its the tank vent valve. I learned it will start if you floor the pedal and then crank it. I went back with jumper and sure enough it fired up. Now the $100 part is on order and looks very simple to change. You have been warned!

This is common on a variety of Porsche models, including the 911 and happens after a certain age or mileage.

Cheers,

Was the check engine light on prior to it totally failing?

it has been, however it reads 0491 and 0492 which I believe are airpunps? So was assuming it was either faulty air pump or vacuume leak.

Thanks for sharing the experience. I'll try to remember that one. BTW, the repeated cranking is a good way to kill a starter. It just gets too hot and stays hot if you keep trying it. Good to hear yours survived, but it may have been weakened.

So it warned you ahead of time and you did, what about it?

Vacuum systems are a pain in the *** when it comes to emissions management. There's other posts here on rennlist that mention those codes. Search is your friend, especially if you use the whole code (P0491,etc) when posting/searching.

That and do you know the age of the battery? They don't last forever. If you run it until dead you WILL harm it. Using lead acid batteries below 11 volts will greatly reduce it's lifespan. I've had boats for years and this is one thing you REALLY have to avoid. Any car battery older than 5 years is a gamble. Sure, some folks have fringe examples of getting longer than that, but for the most part if it's 5 years old you should budget to replace it.

battery is solid. Search those codes and says absolutely 0 about trouble starting the car. In fact it says it’s a benign issue.

Now code P0441 would tell me otherwise. Wkearney99- Am I missing something?

The takeaway from my post is..if you have this issue. ...until you get this replacement done, start motor with pedal floored AFTER filling the tank with fuel.

Totally agree. In aviation, you always give the starter a cool-down period if you are unable to start the engine. This has not translated to the auto world, mainly because people just don’t care since a starter failure certainly doesn’t mean an unsafe car (unlike pretty much everything in an aircraft engine).

Good post about starter cooldowns after cranking attempts.

It's an '06.. you know the battery is solid because it's already been recently replaced? With batteries, ugh, you really can't assume anything. Way too much depends on them. In modern vehicles there's much less margin for error when the battery starts to fail.

When I read codes having already been seen, without other debugging having been done, it raises some questions. When you start seeing emissions/vacuum-related codes it's a sign things are likely going to be an adventure to fix.

Default Code question

Would the P0441 code show up in an OBD port reader or only with a durametric?
I have the no start symptom but my OBD reader shows no codes

thanks

Any code between P0000-P0999 will show up with a generic OBD-II code reader. And the description of the fault is supposed to be accurate. Codes in that range are considered all-vehicle codes - related to emissions. Codes above P1000 are manufacturer specific codes - and they can (and do) vary widely from manufacturer to manufacturer - and even within different models from the same manufacturer. They typically can be read by a generic OBD-II code reader - but for an accurate description of what the code actually means on your year/model/car - Google is your friend.

More than you ever wanted to know about OBD-II:
