Should I buy this Cobalt

Coolant temp sounds like your sensor came unplugged.

I believe this car is a wiring nightmare. It would be easier to get a used harness and throw it in. Make sure every connector is plugged in. Look at the fuse box. Look at the bundle of wires near it.

Could one of the computer be bad since the information center does not read anything correctly?

I doubt it. Most likely unplugged connectors. Somebody had an issue. U can try to see if its bad.

Key on

There is a plug by the firewall. Check that connecter. Unplug it and plug back in fully. Next to fuse box. On firewall

Under the hood or the fuse box in the center console?

Under the hood.

Ecu isn't paired to the motor or your key is not paired. That security light on the dash means it won't crank. So you either news to pair the key or preform a crank relearn.

I started retracing what my brother and I did last night and found that the computer wasn't plugged back in. Now the car cranks itself when you turn the key to on and wont run then keep cranking and stopping for about 1 second on 1 second off until i take the key out
