Young MacGyver accidentally kills a friend in the episode "Blood Brothers". It is the second episode of Season 4.
In the episode, Mac visits the town where he grew up, but he can't shake the memory of the time when he and some friends were target shooting in the woods and one of them was accidentally shot. The wounded boy died because Mac couldn't get him to a hospital in time and the other two friends ran away instead of helping. With that in mind, MacGyver attempts to make right by trying to prevent a couple of teen boys from being killed by crack dealers.
The Stringer
Actually MacGyver doesn't like guns and refuses to carry or use one because of a childhood accident with a revolver that caused the death of a friend. It was shown during the fourth season in episode two "Blood Brothers" It shows MacGyver going back to his home town and getting together with two childhood friends to open a "time capsule" and it is shown through their memories/flashbacks from when they all were kids of the accidental death of one of their friends, caused by a falling gun that hit the ground and went off hitting the young boy "Jesse." MacGyver tried to save his friend but the boy died before help could be reached. However in the pilot episode MacGyver is seen firing a gun (AK-47) at some Russians soldiers. This was before the fact that he didn't like guns was established.

In the majority of episodes MacGyver uses Victorinox Swiss Army Knives. The opening title sequences does show a clip where he was using a Wenger knife, but most of the time it's victorinox. According to the MacGyver Online web site which has a list of all the knives used in each episode the most commonly used knife was the Victorinox Spartan.
No there is not an episode which explains his fear of heights. Probably because it's a fairly common phobia and most phobias are not caused by an actual experience, but more from a psychological fear or mindset.
