There is no power going to the ECM on your 1997 Blazer The fuse is good but you don't know what else to check?
If the PCM isn't returning signal, even with a functional fuse and a clean 12v signal from the battery (If you are unsure of the battery's health, perhaps a new one is in order as well. the PCM requires a clean, dedicated signal, and an older/corroded battery can cause a weakening or interruption of the PCM 12v signal), It is possible the computer has been accidentally flashed over. A good next step would be to remove the PCM from the vehicle and bring it to your local GM dealer, preferably a GMC/Chevrolet (since they'll have the most knowledge of the workings of the 4.3 Vortec motors and electronics) dealer with a Tech II scan gauge. They will be able to tell you if there is an issue with the PCM.
