Need to know what year 4.3L Blazer to answer that.
Sounds like you got some bad gas and clogged it.
That vehicle has throttle body injection. It has two injectors on the top. You say one doesn't spray. If I remember right, each injector has its own electrical connection. Switch the connections from one to the other then run it. If the same injector doesn't spray you have a bad injector. If the other injector doesn't spray you may have wiring problems or a bad pcm.
What else can I help you with?
