If your Blazer has spark and runs, the crankshaft position sensor must be good. Or you can scan for code P0320, which would indicate a failing sensor. If for some reason you don't trust it, you can get a replacement for $40 but on some engines it is hard to reach. And I always tell myself: "If it ain't broke, don't fix it".
