Need help 2005 SR5 Starting issues.

Just the other day my truck is a no start no crying. So I went through the usual routine clean my battery post charge my battery left it on charge for a bit come out to try it and only one click. I think it possibly my starter relay so I pull that one out go buy a new one put it in and immediately the truck starts turning over. Of course it wouldn’t start because the keys are in my pocket outside of the vehicle. I’ve changed the ignition. The starter. The starter relay. Every time I plug the relay in, it turns over continuously. Even without the key in the ignition. I plugged my obd2 in and it gave me codes p0340 and p0345. What the hell is going on here?

 

Well, I sure hope it wasn't crying!

Kidding. So if it was giving you a click at the starter, that means your relay was fine. That click is your starter not having enough juice to fully spin. I'd load test your battery cause I'm betting it's toast.

 

Haha! I’m using talk2text this morning. My battery has been showing me 12.6 volts. It’s a autocraft platinum agm. I mean it’s possible. Suppose for a sec that my battery is shot. Why in the world is my truck automatically spinning over when the starter relay makes contact in the fuse box?

 

Welcome aboard from SoCal.

 

Your new relay could be stuck closed. That would make it try and start with no key.

 

Have you tried jump starting it with some jumper cables?
