2006 Aveo 1.6 manual-Changed water pump but messed up timing marks

[rrb6699]

I tried to change the water pump. but when I put the timing belt back, my timing marks are all off. I thought I was careful putting the belt on. I tried a few things but couldnt line them up.
anyway, I couldn't work on it due to darkness.

what do I need to do to set them back in synch?

I stopped once I noticed this. I still have things apart, but, just put engine mount back so my jack doesn't support the engine all night.

I didnt think a water pump job would be this difficult. I watched how it was done so decided to try. probably messed things up pretty good this time. I need it back on the road asap too.
