First Porsche - Stuck at gas station
 

I just purchased my first Porsche a 2000 Boxster and it runs great but yesterday I got stuck at the gas station after filling it up. The car would not start after I filled it up, it would just crank. If I pushed the pedal while it was cracking it would start, run rough and just die a couple seconds later.

After about 15 minutes max sitting the car started and ran fine.

When I purchased the car it has a CEL with P0446. I have cleared the code and changed the gas cap before I went to the gas station yesterday so the gas cap was not an issue.

I did not get a CEL back on since the problem with starting the car yesterday.

Any idea what my next part to check/replace should be? Looking around I see others talking about the EVAP shut-off valve, EVAP Purge Valve (Which I can not find the part to order) or the Fuel Tank Bleeder Valve.

Any input is appreciated.

does the tach jump while cranking? If not, could be a bad Crank position sensor

Bad EVAP purge valve.

Where do I find this part? I have been looking for it around and I can only find 2 used ones on ebay.

Can't do much better than this: https://www.pelicanparts.com/More_Info/99660520301.htm?pn=996-605-203-01-OEM

OEM part number is 99660520301

I have found that one, but there is one that is under the left side intake plenum that is a Bosch part that is also a purge valve and I can not find that part.

And is the problem im having the part you have there, or the one under the intake plenum that I can't find.

Not that valve.

This one (under the left side intake manifold): https://www.ecstuning.com/b-bosch-parts/purge-valve/0280142300sj/

Search for the part number (bosch 0280142300SJ) and you can find it for less than $30. ;)
Sometimes they can just be blown out/cleaned, so you may want to try that first.

Is that the correct part for my 2000 986 base? The part number they list there is different from the one I have come across. I also come across 0280142380.

Thanks

I don't want to jinx it, but I replaced this part on my Boxster last week and I have filled up twice so far and have had no issue starting the car right after.

The part I took of the car did not seem bad but had a part number I never seen in my research so I assume it was changed at some point before.

But thanks for the part number and advice on what to change.

Does this require removing the left intake manifold?
