2001 Saturn SC2 Question: ECU repalcement

I replaced the ECU and now the car will not start. All the numbers match the old ECU. I put the old one back in and it will start. What may cause thisissue with the new ECU? -

It is possible that it needs programmed upon installation. You may want to consult a Saturn specialist. Here is a link to some shops near you... https://repairpal.com/directory?address=23231&car_brand_names=Saturn -
