A litany of things could be wrong here.Lets just start with the basics.
Check your connections to the battery terminal: Are they clean and tight?
Are any of your fuses blown?
Is the battery brand new and under warranty? If so, have it and your old battery tested. (many places will do this for free)
If those are all moot points, have a diagnosis run on your car. You can take it to a dealer, and they will do it for about 80 bucks. Or you can jump on eBay or other sites and try and find an ODB diagnosis tool for about 30 bucks and you can use it whenever you want. (they arent as fancy but they do the job)

AnswerIf you have changed the battery and the engine cranks but doesn't start, the security system may be doing it's job.Turn the key to the "RUN" position momentarily, then back to "OFF". Wait 15 minutes and repeat the process... wait 15 more minutes and repeat the process again. After the third cycle of placing the ignition key to the "RUN" position, then to "OFF" and waiting 15 minutes, the car should then start fine ...
1. Turn the ignition key from "OFF" to "RUN", then back to "OFF" 2. Wait 15 minutes
Repeat steps 1 and 2 three times... then try starting the car.
disconnect your battery and touch the cables together then let the car sit with the battery disconnected for 30min
Replacing battery terminals??? How did you accomplish that. Do you mean you replaced the battery or are you referring to the battery cables? If you replaced the cables are you sure you have them connected correcty and tight. Especially the ground connection. Take a reading with an ohm meter from the neg battery post to the engine or chassis. If the circuit is open, you have a bad connection.
When replacing battery, when servicing some part of the engine, or when the vehicle is not going to be started for over one month.(keeps the radio memory from draining battery)

My check engine light came on because the terminals were not connected tightly. no. quite the contrary. if you have a "check engine" light on, disconnecting, or in this case replacing the battery will turn it off. you have a different problem.
9 times out of 10 replacing the oxygen sensor will do the trick. Or, try disconnecting and reconnecting the battery.
It may need replacing or it can be the alternator is overcharging the battery. Have the charging system checked out. The alternator should output from 13.5 to 15.5 volts with the engine running at idle.
Extreme cold puts a greater strain on the battery especially when the engine is cold. The oil in the engine is cold and does not flow as well as it does when it is warm. This requires more torque to turn the engine over and that puts a strain on any battery that is not in tip top shape. You either have a battery that is weak and needs replacing or the battery has too little CCA for the engine. Get the highest Cold Cranking Amps (CCA) rated battery you can get that will fit your car. The more CCA the easier it will be for the battery to start the engine when it is cold.
If you use the radio without the engine running you will eventually discharge the power from the battery. It should be fine for a couple of hours, If not, your battery may need replacing.
Disconnect your battery, and leave it disconnected for at least 24 hours. The battery backup on the computer will die after 24 hours, at that point, the service engine indicator is reset.
until code is set again
unplug your car battery
