Hi, If the problem is associated to you replacing the battery, then it could be a few different things. 1) Is the replacment battery fully charged? If not, charge and retry. 2) Are the positive and negative battery cables connected correctly to the battery? With this you have to be sure that you have a good connection to each battery terminal. Try removing the cables and taking a wire brush to the terminals. Once clean, reconnect them and try to start again. 3) Is the positive cable broken? If broken replace the cable. 4) Is the negative battery cable broken or properly connected to the car? If broken, replace the cable. Good Luck!

Possible poor battery cable or cable connection. Remove the cable terminals from the battery, always remove ground or negative first! Use a small brass brush to clean the terminals also clean the connections too. Next follow the ground cable, to where it mounts to the body or engine. Remove this connection and clean both surfaces of cable and mounting point; re-install with proper torque on bolt. Be certain to check the cables for any short bends, thses can cause the inner cable to break and have poor connections Look for a gronding strap that runs from the firewall to engine, insure its clean with good connections. Then check the connections at the alternator, be certain that these too are clean and tight. After which reconnect cables to battery positive first ground last. Recharge the battery if she works great, you found the problem. If you still have issues it would appear your battery has or is loosing a cell and may need replace. This can be checked at an autoparts store. Lastly may be issues with charging system, alternator?
