Hi David .

This we see quite often and in most cases the problem is a bad ECU.

But what i would do first id pull the ECU plugs and clean with contact cleaner then replace ,

but first disconnect the battery and press on the brake pedal to discharge any electric static from the system.

after cleaning connection reconnect ,

Reconnect battery and retry .if still no communication and no check engine light remove ECU and have it checked and repaired .

For further assistance with this issue please get back to me with the reply box below .
This is not a one answer and done i/we will stay with you until the problem is sorted out .
