Older models of the Pi4B 8GB need to have their boot loader updated to boot from USB. If your image won't boot remove the USB3 drive and use rpi-imager to flash Pi 4 EEPROM boot recovery to an sd card.
Plug the Pi into a monitor, insert the sd card and power up. Once you see a green screen you should be good to boot from your USB3 drive. Newer versions are shipping with a USB boot capable boot loader. Feeling lucky?
