If you have bad fuel in your blazer first you could drain all the gas out of the gas tank and then if you have a carburetor take it off and clean it up with carburetor cleaner and blow air through all the jets and if you wanted to really make sure you could take out your spark plugs and get a torch and burn all excess oil/fuel off sparkplugs then reinstall and then put good gasoling back in another thing you might want to either clean your fuel filter or replace it
