Faint means dizzy, light headed; having little strength or vigor: “After hearing about the death of her son, she was quite faint.”
Feint, on the other hand, means trick, ruse, stratagem; a misleading movement or attack directed toward one part to draw defensive action away from the actual target or objective: “The baseball pitcher usually made a feint just before he threw the ball to first base.”
I thought I would faint when I saw my friend feint a heart attack and fall to the floor.
