I have another post up in this section about not being able to get my coolant temp guage working but now my issue is that I have power to my obd2 port but no serial data, I tried my scanner and hp tuner but can't connect to the ecm.
I have a plug and play harness from Current Performance and I made sure to wire in all the serial data wires on the C101 connector with the harness and now I have no Idea what to check from here, any help or reccomendations would be appreciated, especially since I can't get a hold of current performance tech support over the phone now...

Vehicle info: 2000 Chevy S10 Ext Cab (4.3 Vortec originally) 5.3 LM7 and 4l60e currently in it.

CPW is pretty responsive with email. Check for continuity between the ECM and the OBD2 port. If there's not start checking for continuity at each in line connector. Start narrowing it down and you'll find where the problem is.

CPW answered and you won't believe how easy the fix was, apparently they had a bad batch of C101 connectors that were mislabled and mixed up wires 4 and 11 on the connector itself, I just hope that anyone that bought the harness at the same time that I did gets to see this post and know what the issue is.
