That was my whole problem. That wire is the ground wire to firewall. Someone had left it like that. As soon as I grounded it, went over and started right up

Hello, I have a 2004 Avalanche, I have a no crank no start problem. turn key, everything goes away on dash, no crank. Let key go. All lights come back on. Re set passlock and that’s all good. Still no start. Nothing. Zero. Zilch battery is fully charged days battery charger. You would think that it would start? here is a pic of a wire I found just laying around not connected. Take in mind I just bought this today! where does this wire go?
