2004 Honda S2000 — long crank only after filling the fuel tank

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2004 Honda S2000 does it — then decide on parts. That's the branch I'd chase this week. Have you gotten a second quote in writing? Make the next action something you can finish this week. I'm in no rush to be a hero on it.

Log the conditions before you spend. Move a coil or plug on the 2004 Honda S2000 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. On “long crank only after filling the fuel,” that was the fork that mattered for me. That's the sequence I'd use. Might be overthinking it, but I'd rather overthink than overspend.

Start with the test that can prove you wrong. Move a coil or plug on the 2004 Honda S2000 if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. No need to make it theatrical. Your commute and mine probably aren't the same, but the test still applies. I'd rather look cautious in this thread than stuck later.

If it were in my driveway, write temp, speed, and in-gear vs coast when the 2004 Honda S2000 does it — then decide on parts. Save the big job until that test fails. This is from a 2004 Honda S2000 in Columbus with 215,000 miles. That's the sequence I'd use. Not trying to scare you — just skip the expensive first guess. If the story changes I'll post the new data.
