Hi and thanks for using 2CarPros.
Based on your description, it sounds like the battery is weak. That is the first thing I suggest checking. Also, most likely you had the battery disconnected when doing the work. Make sure the cables are clean and tight.
Here is a quick and easy way to test the battery:

If this isn't the issue, let me know. Also, let me know if the starter is properly cranking the engine.
Take care,
Joe
