What was the reason for replacing the computer?
Have you performed basic testings and what is missing causing the non starting?

Did you install a NEW ECM from the factory or a used one from somewhere else?

the unit was purchased at Advanced Auto. Not new but rebuilt. The car was losing power while driving. With stop and go traffic. And would not start after turning off and then trying to start again. With a jump,it would start. And it would also start after a couple hours of being idle. We took it to a mechanic and he replace the crankshaft sensor but he said that afterward the car did stall once. And that he did not think it was the sensor that he felt the computer should be replaced. So that is what I did this morning. Any suggestions?

I don't know how he conclude any of that. If the engine will start with a jump, then you have a battery or charging system issue. I don't see where you get computer from that
