The 2000 4.3 will fit in the Blazer. If the engine previously in the Blazer was a 4.3, it should be a direct changeover. Any parts differences you can use the parts off the old motor to make it work. Some connections may be different, but can be worked around.
sounds like you know what you are doing, sometimes the codes have to be removed after repair, i'm not sure whether or not your vehicle requires this. If it is just a light bothering you try and clear the code and see if it comes back. Some Advance Auto or O'reilly has a tool to do this free of charge
if it does not start after you check your distributor cap that means you took the car out of timing, when you put the distributor cap back on you did not put it is the correct position, now you need a mechanic to get the timing of the engine
That's what it looks like.
Ligh?
