My 1996 Chevy S-10 Blazer has been hard-starting lately What gives?

This morning it took several tries and pumping the gas pedal to get it started. When it did start, I heard something under the hood making a sort of high-pitched grinding, tapping noise. I turned off the engine and tried again and got the same noise, this time with a electrical burning smell. Any ideas on what this might be?

check the alternator or belt it may be a tensioner going out or an alternator bearing.
