Easy computer repair.
The reason I am writing about it is because I remember reading instructions how to repair Mitsubishi 3000GT comps which have exactly same problem. A lot of different cars were mentioned there not sure about Corvettes.
So before throwing away and buying new ECM, take its cover off and look if you can find blown capacitors or some parts which look burned.
Search internet and youtube about capacitors.
Sometimes we make repairs harder than they need to be. Just find the bad component, replace it and move on.
