Remove F7000 and check C7050 and L6900 voltage.
What about SMC_4FINGERS_RST?

Try changing U7000.

Post exact ohm resistance over C7020/23.
Please check again (correctly).
Keep in mind, I didn't ask to check in refference with ground.
Too many times we talked about this checkings on the forum...

Change U6903 too.
Be sure all R6910-13 have correct values.

"PPVIN_G3H_P3V3G3H is 3.9v"
Still same?
If yes, change R/D6902.
Remove R6915 and check C6915 voltage.
"R6910/13 have correct values"
I said R6910-13, 4 resistors!

You can't get PPBUS_G3H without 3V3_G3H.
So you have a problem on the 3V3_G3H power rail, after R6915.
Try injecting 3.5-4V there and use IR camera.
It allows you to detect small temperature differences.
Remove CPU heatsink first and disconnect any cable from the MLB.

No need to resolder R6915 yet.
Machine boots now without battery?
Check diode mode to ground and voltage at SCL/SDA lines of battery bus.
