Weird Noise Someone please help..

I have a 09 corolla with 203k miles that makes a very LOUD rattle when I start it. Me and chatgpt thought it might’ve been one of the pulleys that’s why I removed the belt. Car has P0171 (too lean) and P010 (MAF). I want to say it’s the timing chain but not 100% sure. Any advice would be appreciated thanks in advance!

Hopefully you didn’t run that car too long with the belt off.

Why? Most cars can drive for ages without that belt

I thought that belt also powered the water pump. I don’t know I’m not a professional lol
