Mac Pro Retina 13 inch Early 2015 not powering on

[arnonabuurs]

Hi Guys I have a retina 2015 that was liquid damaged, we cleaned it and all was working fine for a month, after replacing the battery. Now it does not want to start when pressing power on the keyboard. When pluging in the charger it starts up and works fine. I also tried another keyboard and trackpad but still doesnt respond to power key. Logic board issue?

Check the connector.
Does shorting SMC_ONOFF_L to gnd turn it on?
Once running does pressing the power button do anything?
