2013 Toyota Prius — no crank with full dash power, then it starts later — Boston owner

I'd want a measurement, not a hunch. Capture voltage while the 2013 Toyota Prius is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. This is from a 2013 Toyota Prius in Boston with 78,500 miles. Take it or leave it — that's what I'd do. If that fails I'll eat the diagnostic fee.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2013 Toyota Prius does it — then decide on parts. Don't erase codes until someone who can help has seen them. This is from a 2013 Toyota Prius in Boston with 78,500 miles. Not gospel, but it saved me a headache. Cold start is when I can actually reproduce it.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2013 Toyota Prius is losing coolant with no puddle. Save the big job until that test fails. This is from a 2013 Toyota Prius in Boston with 78,500 miles. Do that first. Video is ugly but it shows the hesitation.

I went back under the 2013 Toyota Prius and it only happens after a heat soak, not on a cold start. Trying not to diagnose from the couch.

Intermittent stuff lies if you only catch it once. Move a coil or plug on the 2013 Toyota Prius if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. On “no crank with full dash power, then,” that was the fork that mattered for me. Any freeze-frame data saved? Climate here is different, so treat that as a local data point. Happens in gear, not in park, for what that's worth.

Log the conditions before you spend. Swap the cheap/easy piece first on the 2013 Toyota Prius and see if the fault moves. That's the branch I'd chase this week. On “no crank with full dash power, then,” that was the fork that mattered for me. That's the whole play. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. If a shop can't duplicate it on the 2013 Toyota Prius, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. This is from a 2013 Toyota Prius in Boston with 78,500 miles. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. I'll poke at it this weekend.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2013 Toyota Prius catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. If it doesn't change the out-the-door or the repair estimate, it's noise. Checking again after work.

Start with the test that can prove you wrong. Swap the cheap/easy piece first on the 2013 Toyota Prius and see if the fault moves. Don't erase codes until someone who can help has seen them. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. Not interested in a five-hour wait for a shrug.

If it were in my driveway, write temp, speed, and in-gear vs coast when the 2013 Toyota Prius does it — then decide on parts. You'll know quickly if you're on the wrong tree. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd sleep better after that step, even if it finds nothing. I refuse to clear codes until someone else sees them.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2013 Toyota Prius, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. This is from a 2013 Toyota Prius in Boston with 78,500 miles. Stop there until you know. A day of patience here is cheaper than a wrong part. Heat soak after errands is the other window.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2013 Toyota Prius and see if the fault moves. You'll know quickly if you're on the wrong tree. Write the result down so the next test isn't a repeat of the last one. Not driving it hard until I know more.

Cleared nothing. I want service to see the alert on the 2013 Toyota Prius first. Parking it somewhere I can hear it better next time.

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2013 Toyota Prius is losing coolant with no puddle. Save the big job until that test fails. If it doesn't change the out-the-door or the repair estimate, it's noise. Parking it somewhere I can hear it better next time.

Ask what changed right before it started. Swap the cheap/easy piece first on the 2013 Toyota Prius and see if the fault moves. If the cheap test changes it, stop and reassess. Had a similar mess a couple years ago and that's what finally sorted it. Make the next action something you can finish this week. I keep a notes app thread for this now.

Intermittent stuff lies if you only catch it once. Two 2013 Toyota Priuss can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. On “no crank with full dash power, then,” that was the fork that mattered for me. That's the whole play. Doing the boring step first on purpose.
