I will tell you what my trainer did with me. As I also had these issues with my sheltie. He would just stop, buck, and would absolutely not do it.
What she had me try is to leave the pressure on the lead, so it is taunt. Most of the time we would think not to do this, because the stress that is going through the lead. BUT Aztec, being smart, would stop because then the pressure would leave when I would go to him and try to coax him to behave.
So hold the leash taunt, and let them sit or be wild for a second or two. Then ask him to "come". If he does listen and comes to you, treat him and praise. At the time I was having to do this probably 5-7 times each time I tried to do something with him, but eventually it clicked and he is lovely on lead now. When the trainer first brought it up, I thought it was a little odd, but it actually worked in Aztec's case.
