Raspberry Pi 4 8 GB not booting with GPIO connected

Hi, my RPi is working perfectly and has been for some time. Recently I started building a weather station and connected a bunch of sensors to the pi. All the sensors were tested with a python program individually and they work. I shut the system down.

The next day, I booted up the pi and it hung with a blank screen and no disk activity for ages. I powered off, disconnected the power leads (5V and 3.3V) and then booted the pi. Everything worked fine. I reconnected the two power leads and the sensors are working again.

Why should the pi refuse to boot with the power leads connected?

Thanks fr your help.

Hey John,

Welcome to the forum!!

Usually a short across the power pins would cause the Pi to turn off. Leaving it on a metal surface will also cause shorts and cause the Pi to not boot.
