820-2879 MacBook Pro 13 2010 no post

I have a MacBook Pro 13 2010 that doesn't post, u6100 has 0v voltage on pin 5 (SPI_MLB_MOSI) and on pin 6 (SPI_MLB_CLK) and on pin 2 (SPI_MLB_MISO) vcore is 0.99v

ppvcore_s0_cpu voltage drop is 0.027

Macbook was liquid damaged, before cleaning it did 9 beeps "3 short beeps - 3 long beeps - 3 short beeps"

Measure Vcore while turning it on. Does it drop from 1.15 to 0.99V after a few seconds? USB mouse lighting up? Resistance to GND on 3V42 rail?
