NAFT1

Thought I'd post here before I tried in the regular 210 forum. As the title states, I get no connection from the OBDII port with two different scanners. I don't have the Star shaped connector for the diagnostic port under the hood yet. Checked all of the fuses in the K40; any ideas of other common failure points to check before I start spending money replacing stuff? I'll need an inspection in about 8 weeks to renew my vehicle registration and that involves a readiness report from the ECU.
