Obd2 communication

Topic starter

Greetings. I have a 1996 chevy p30. I converted into a food truck. It has an obd2 connector but no communication with any scan tool I use. There us good power and good ground. I can't find anything on Google and I don't have access to all data to figure out what the issue might be. Any ideas?

I know some vehicles built in 96 were still obd1 and never made the conversion until late 96 or early 97. But it does have an obd2 connection. It just will not communicate to the computer
