Hondata

I don’t have access to another vehicle to try with. Kswaps aren’t common in Vermont. I have a new rywire engine harness. I bought my swap harness from hybrid racing. Hydrid racing ground cable set. Everything tests well.

I mean the grounds are definitely good. Even added an extra to be safe. It seems like the kpro is bad

Yes through the usb. With it usb unplugged the fuel pump relay with click then car can start, then will click again and car dies. The relays are good. It ran great the first few start ups then this happen. It’s a brand new kpro

My car will not run unless plugged in. Ecu clicks then car dies. Will click again and car starts. Did I get a bad kpro?
