Nice work, my daughter's car has the no crank issue. Instrument panel lights up and I hear a little click but nothing when you turn key to start.
Bro... My Corolla died on me at work a month ago,it wouldn't crank at all. I replaced the starter relay with one from AutoZone but still no start. I checked the connector to the starter for power and it wasn't receiving any. I started believing the key somehow got deprogrammed but that was false, the security light would turn off when the key was inserted. I'm going to order an OEM starter relay and hope it works. I've been stressing like crazy. Thank you for this video so much! I hope I get it to start up without giving in and sending it to the dealership 🙏
change the relay for a 100% American one so you don't have any more problems. Just kidding, thank you very much my friend.
2003 corolla, it has the exact same problem. I though it was the starter. I replaced it and still the same issue. Excellent analysis. Thanks a lot!
I’ve been trying to fix my 2007 matrix for days. Watched many videos. Yours was definitely the best one. Starter relay was bad. Thank you mucho!
I'm thinking about buying a new stater but everyone in the comments telling me others wise
I share your frustration at having to diagnose an intermittent problem. I really like the fact you used a test light, which is a tool much less prone to misleading information. The S post should have no voltage until the driver turns the key, closing the relay to send current down to the S post. So I'm a little puzzled at how you measured voltage there even before the key was turned. Maybe you had the test light hooked to bat pos? But if so, the test light should have lit, at least, before turning the key, provided the S post connection to battery was secure. Maybe you had the S post wire disconnected, the test light was hooked to the end of the wire, and the other end of the test light was hooked to bat pos? Or maybe you had the test light connected to the B+ post?
Those relays always have bad contacts when they have black carbon buildup, will cause intermittent error. If you clean those contacts with sand paper to expose new metal they will work but over time the black buildup will come back and intermittent problem comes back until you clean them again. Everything requires maintenance.
I replaced starter relay, it worked once, then same issue again. I took it to the shop and they said it’s the battery (even though I knew the battery was fine). They replaced it and it still doesn’t work.
Thank you for posting this, I’ve been having the same problem, I hope it’s that easy of a fix. When you show your troubleshooting it also helps me learn how the systems work. Keep up the good work I really appreciate it!
Nice show fella. You didn't know and I didn't know. I was feeling it. You did me a service to see a good progression of thought. I was thinking starter motor. You had the answer. The started motor relay.!
Best video on the subject, thanks
Good video and your experience is paying off. Keep it up!
Solved my toyota problem thanks very much 😊
Great job my friend... I have learned something new to be aware... relays. Thank you
I learned a lot from you brah. You’re pretty awesome. Great work.
Thanks for this video, I had a similar issue that began right after I washed the engine.
Nice. The control side of the relay worked, so that would explain working signal on scan tool. The power side of relay is was went out. Excellent job diagnosing the problem.
Thanks for this! Just saved me a ton of money on a tow
