2023 Subaru Outback — long crank only after filling the fuel tank

RustBeltMom362Community StarterJan 16, 20262023 Subaru Outback WildernessSeattle
The car starts normally most of the time, but after filling the tank it occasionally cranks longer and runs rough for a few seconds. Could EVAP/purge behavior cause this, and what would you test? I am in Seattle. Mostly looking for the right next step. Mileage is about 138,000.

I wouldn't throw parts yet. Move a coil or plug on the 2023 Subaru Outback if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. This is from a 2023 Subaru Outback in Seattle. Had a similar mess a couple years ago and that's what finally sorted it. Cold start is when I can actually reproduce it.

I wouldn't throw parts yet. A pressure test beats staring at a dry driveway if the 2023 Subaru Outback is losing coolant with no puddle. That's the branch I'd chase this week. Learned this the expensive way on a previous car. I've seen both outcomes, which is why I'd test instead of assume. No warning lights, which is why I'm documenting it.
