2023 Toyota 4Runner — long crank only after filling the fuel tank

BatteryEnthusiast712Community StarterFeb 18, 20262023 Toyota 4Runner TRD ProAustin
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?

Log the conditions before you spend. Loaded-suspension checks on the 2023 Toyota 4Runner catch play that a wheels-hanging inspection misses. Save the big job until that test fails. On “long crank only after filling the fuel,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. If the story changes I'll post the new data.

Start with the test that can prove you wrong. Move a coil or plug on the 2023 Toyota 4Runner if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. This is from a 2023 Toyota 4Runner in Austin. I'd want a dollar figure or a measured spec, not 'should be fine.' I'll update if anything new shows up.

Ask what changed right before it started. Get a real battery/charging test on the 2023 Toyota 4Runner, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. If they can't show the line item, I assume it's hiding. A day of patience here is cheaper than a wrong part. Parking it somewhere I can hear it better next time.
