It’s the big plug/connection where the engine wiring harness plugs into the DME in the box that’s in the cowl section of your car, right side, up by the windshield. Disconnect the battery, take the cover off, find the DME and pull that plug off. Inspect the DME and plug for corrosion, bent pins/tabs, water intrusion, etc.
In the spirit of doing the easy stuff before the hard and expensive stuff, You may want to check all your grounds. Especially the ones under the coil covers. Though the fact that your OBD port isn’t working seems to point to the DME perhaps…at least in my one brain cell. Can you access other modules, like the transmission module?
My single cylinder misfire turned out to be water intrusion into the actual harness during a coolant pipe job I did.
