Once charger in plugged in, immediate high fan seconds later boot chime then 3-4 seconds later shutdown. No Green light.

PPBUS_G3H?? For future reference, does boot chime imply this??

So it looks like the keyboard was shorted and making it restart. Now to solve other issues.

Ppbus_g3h is one of the power rails on the board , you can find the voltage on the rail using a multi meter. Chime . Aka the sound emitted by a healthy macbook right after powering on
