Update: I've checked all fuses again just to make sure. I pulled a few OBDII plugs from 99 v70s at local junkyards, and still nothing. The code reader is getting power, but the data link cannot be established.
I've tried 4 different code readers, three different OBDII plugs/pigtail wires in the center console. Nothing.
Could it be the ECU itself in the engine compartment? Or am I possibly looking at a full wiring harness replacement?

You checked everything except what i told you to do.
Again.....K-Line goes through immobiliser module(immo ecu)
Could be immobiliser fault...or k-line from immo ecu to engine ecu.

Bumped thread for you, T.
See the induction failure thread I bumped, too.
We need friends in RI to watch that PnP for us - only one in Northeast.
