Starter Issue but how big?
Year and a half ago my factory starter failed on my 2003 Civic LX. Was ways away from home so had to tow it as close as I could which ended up being a Firestone about 15 miles away from home. Got the starter replaced, they did a diag and said everything looks good. A few days ago, car won’t start at first key turn (no click from the starter either). Once it started and even if it sat off for a bit, would turn over just fine.
Yesterday I get in, turn the key and the starter starts whirring and engine won’t turn over. I try to start it again and starter stops until I try one more key turn then starter starts whirring again even when I take the key out of the ignition. Everything lights up fine on the dash and head/tail lights. Wheel turns, can shift into neutral etc but engine won’t turn over and starter won’t stop. A few more key turns and still starter won’t stop. Immediately disconnect the battery and let things sit. Anytime I reconnect the battery the starter kicks back on so I leave it disconnected.
I get a tow to nearby Firestone, they say they’ll honor the warranty on the starter but think it could be electrical. I forgot to check fuses and relays so not sure about that but almost all of my research is saying either a failing solenoid in the starter, bad fuses, or bad ignition cylinder. Most leaning toward starter. Firestone guys there are just mechs and their electrical guy isn’t in till Tuesday so they refuse to work on it until they can run an electrical diag.
End of the world case is the cable connecting to the starter in the wiring harness being bad but I haven’t found anyone with that issue on the internet in all of my searches. Is Firestone just erring on the side of caution or is there likely a bigger electrical issue?
