Timing chain replacement

After getting OBD code P0016 on the car listed above I spent a few days erasing the code and driving the car. The car was running fine, but I was afraid of damage, so after checking a few things, I took the covers off to replace the timing chain and tensioners. Since I had no knowledge of this as it was the first time, I didn't bother to make any marks. The marks didn't line up so put the chain on the crank and the intake (diamond) and moved it to mark. Then I tried to do it to the exhaust (triangle) to shaft to try to get the mark lined at 2 o'clock but it wouldn't move clockwise so I stopped. Then I had a friend with knowledge come and help me, so he put the chain on, but the exhaust (diamond) would not move to 2 'oclock position. It is more 1 0'clock and the diamond is at 2 o'clock. So when we put the chain on, we had to pull the triangle to the right because the still position, the chain would not reach from the 5 o'clock to the triangle mark, which would be 1'oclock. So we put it on the marks after pushing it over. Anyways, after so many revolutions, the chain marks are all 3 a tooth behind the marks. Never match, chain and sprocket marks. We did a few more revolutions and still all 3 on the tooth before the mark. We tried quite a few times that he finally said, you are going to have to get someone with more knowledge than me. Any idea why that happens? Thanks. I don't know if you can tell on the picture but the one on the right is only at about 1 o'clock. They are just sitting in place and lightly bolted, not torqued and the chain is off btw.
