board is water damaged.

board was not getting green light on magsafe. checked pp3v42 and was only getting 69ohm (pretty close to short to ground). i injected 3.5v but its not drawing enough amps to heat anything up. Any suggestions?

High value will not heat anything.
However, not bad idea to try, as sometime a chip can get hot because of avalanche process; only detceted under voltage applied.

Inspect board for suspicious caps, affected by corrosion.
Lift L7095 and check where the low value remains.

Freeze spray might help detect heat. In such case, check for shorts on PPVRTC_G3H, and PP3v3_SUS as well. If all shorted, trash this. If no, then inspect for short near the SMC it could be pulling 3v42 down
