This was liquid damage, after cleaning in ULSC the DDCIN was missing due short on C7190 which blow D7105 , replaced C7190 and D7105, now getting 20v , still no power, checked all other 3v42 PPBUS all there, but not getting any voltage on PP3V3_S5 and PPV5_S5 .
no short to these lines or any damage chipset , i soldered wire from C5125 (PP3V3_S5_AVREF_SMC_ and got 3.3v now to PP3V3_S5 but PP5V_S5 still missing , when inject 5v to it still no fan spin or heat on cpu ?

Stop to do things like that.
AVREF of SMC is a low power rail...

Do you have magsafe light?

Dead D7105 usually meant burnt U7100 and R7105 too (open).
Any voltage at CHGR_DCIN?
Check for short if not.

Post voltage to F7140/41.
If nothing, post resistance to ground.
