Starting problems

[Z32man]

Ok so I just rebuilt my engine. I put it all together and tried to start it and when I turned the key nothing happened and the lights got dim. So I decided to jump start it and I hooked it up and tried again and the same thing happened. So I waited a little longer to see if the battery would charge. When I tried the last time I turned the key and this time nothing happens. When I put th key in I still hear the bell ring but once I turn it nothing happens. None of the lights turn on like it doesn't recognize it. What do you guys think?
