Please add some details. "Won't start" can mean multiple things. Does the starter crank the engine, but the engine doesn't run? The starter fails to crank the engine? Have you checked the fuses? There are going to be multiple blown fuses, both under the hood and inside. Do any other systems work or not work, such as head lights, radio, heater fan, etc?

Why was the jump-start initially needed? Was this a one-time thing, such as the head lights were left on, or have you been dealing with a weak battery for some time? Any other symptoms related to this problem?

Please list the engine size in case I need to search for electrical diagrams. Many electrical circuits are different depending on the engine that was used. Have you done any testing so far, and if so, what were the results?
