Do you have spark? I don't think you were clear about this in your question. If you have spark, then spray some carb cleaner in to the throttle body, if the engine runs for a little while and then dies, you have a fuel delivery problem. Also get any service engine soon codes, if you have any, that will really help as well.

i see you changed your wires and plugs, but did you put the wires back in the correct firing order? it is very easy to put the wrong wire in the wrong place if you are not careful...you didn't mention anything about replacing the rotor only distributor cap...if you are 100% sure you put the wires back in the right order and you did replace the rotor, go back and ONE BY ONE check to see if the metal tip is far enough out to properly connect to the spark plugs, and also to distributor cap. Sometimes the tips tend to be a little too far in the boot and does not have that snap effect when connected to the plugs and will cause your vehicle to lose power because the spark arcs too much from metal tip to plug. And check to see if you have the correct fuel pressure for your blazer, you could have a dirty fuel filter or fuel pump screen. email me if i can help with anything else, or for further assistance. charlyboy_979@yahoo.com
