2021 Toyota Highlander — long crank only after filling the fuel tank

OldSchoolGeek895Community StarterOct 10, 20252021 Toyota Highlander XLEPortland
2021 Toyota Highlander XLE, about 45,500 miles. 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 Portland.

This is usually cheaper to test than to guess. Loaded-suspension checks on the 2021 Toyota Highlander catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. Happy to compare notes if your setup is different. A day of patience here is cheaper than a wrong part. If this is nothing, great. I want that in data.

Log the conditions before you spend. A pressure test beats staring at a dry driveway if the 2021 Toyota Highlander is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. On “long crank only after filling the fuel,” that was the fork that mattered for me. This is from a 2021 Toyota Highlander in Portland with 45,500 miles. That's the sequence I'd use. Not interested in a five-hour wait for a shrug.
