Liquid damaged board not starting up. I have checked 3.42 line is there and problem with PPBUS G3Hot. Measure at F7040 gives 2.1v and diag mode on PPBUS gives me 0.01v. What would be the next step from here?

That is pretty much a short. Measure resistance from PPBUS to all the coils to see if any high side FETs are shorted.
