Can you have someone take a video of the engine bay when you try to start it?

Did you try the hand crank as suggested?

From 2006 LX Service Manual (You might try to download the one for your year. I'm not sure if the troubleshooting is different). Can you tell if the starter is trying to engage?

That other guys's was obviously not seized. It's interesting his would start when he threw it into neutral sometimes (park/neutral switch on his maybe??). You might try that when you get it. Also actuating the clutch a bunch on yours might point you to that switch quickly. Other than that, I'd just step by step through the service manual possibilities and rule those out one by one using their tests.

Have you been able to turn the motor over by hand yet? What made you think it was the Battery or Starter? Look every hose and wire over well and make sure nothing came loose or got to close to heat and melted. Could be as simple has a ground too. Also if you thought it was the Battery or Starter. It wouldn't be the first time someone bought a new one and it was bad from the Store. Is it not throwing any codes either?
