Thanks for asking your question. I will try and help you out.
Unfortunately I have seen this many times. If the tool says no computer found and it’s a crank no start after disconnecting the batteries. The ecm has lost its memory. The ecm has back up lithium batteries inside. But if they are dead. You will not know until the batteries are disconnected.Please reply back if you need more help. I am happy to assist.
