2000 Volvo S80 N/A Crank, But no spark
 

We just recently replaced the engine for a 2000 Volvo s80 2.9L L6. Everything looks like its been done correctly. All grounds are intact, ecm has been installed correctly, battery was disconnected when doing the engine swap. All fuses check out ok. The problem is the car will crank, but it will not start. Checked all 6 ignition coils and none of them have and spark. Also, We have a snap on solus ultra. We connected it to the car and it will connect to all the options EXCEPT it will not establish communications with the engine and the ETM. If anyone has any idea on what I should check or have experienced this problem before please let me know,.

Anyone? x.x urgently need help

doc, I am not sure but I heard Engines are computer controlled and need update after swap.
