No signal to the OBD-II port and various components not functioning indicates a power supply interruption.
If the fuses were checked good, hope you did use a test lamp or DVOM to test them, the next thig to check would be the connectors between the fuse box and ignition switch.
Can you perform basics testing with a test light or DVOM?
Which engine do you have?
At Data Link Connector, check for battery voltage at pin # 16 if the scan tool cannot power up. If battery voltage is not available, check fuse # 28 (10 A) inpower distribution center.
