'97 Achieva Won't Start NEED HELP BAD

I have a '97 achieva that won't start. Here is the break down of the problem that got it there. When we bought it the man told us it my need a radiator. So after driving for some time it started to overheat. Then the battery stop charging so some times when we were out the car wouldn’t start without a jump or we would have to wait or play with the cable to the battery. So one day it was hard to start when it did get started it stopped because it ran out of gas. We pushed it back in the yard. That was about 5 months ago.
So just yesterday we got a new battery all the lights come on good the radio plays etc.
We put in a new radiator on yesterday also and it still didn’t start the man that was working on it said it was the Starter.
Today we put a new Starter on and it still won’t start. When you turn the key it try to start just a little and then when you try and do it again it just make a click sound. It seems like it could start but it just click at the end. It also seem like something is pulling the battery cause the lights flick off when we try to start.
Please help with what could be the problem.

Did you clean the battery cable ends when you installed the battery ?
Are the cable ends to the starter clean and free of corrosion?
If you have a voltmeter check the large cable on the starter to make sure there is 12 volts there.

You said the car was overheating before you parked it and then it sat for 5 months ?
With the battery disconnected, can you get a socket on the crank pulley and see if the engine will spin around, clockwise ?

Just some thoughts.

where is the crank pulley and do it have to go all the way around

The crank pulley is the big one at the bottom front of the engine, and yes try to go around at least one full revolution. This is to check if the engine siezed up while it was sitting.
