Help, won\'t Start. I went to start the blazer today, and it turns over but won't start. I am getting a spark and the plugs, wires, cap and filter are about two weeks old. I sprayed carb cleaner in the intake and it started and died. That means it is a fuel problem, right. Does that mean it is the pump or could it be something else. I don't know if this is related, but I noticed lately that sometimes when I took off from a stop the blazer would stutter. If I let off the gas and then pushed it again, it would act fine. This started recently and only happened every now and then. Any help is greatly appreciated.
