Been having issues with hondata not connecting to ecu and my obd2 scanner not being able to read codes.

As of right now I have a k24a in my fa5 everything is ready to go the car just won't start and I believe it's because it can't connect to the ecu. Cranks just fine ill check for spark and fuel this weekend.

I tested my obd2 pins and found that only pin 16 was getting power which is the power from the battery so what should I do to figure where the problem is? I was thinking of doing the FCAN circuit troubleshooting but I'm not sure that that's what my issue is.

I've double checked my wiring, all my fuses are good and even put in a new battery. I also put the ecu in another car and it connected just fine so my guess is the power is being shorted on a wire or a module.
