Is it too late for my mom to take my father for child support?

I just turned 19 and all these years my mom didn’t take my father for child support because we couldn’t get a hold of him to get the basic information we need to take him to court. We finally got a hold of his family and they gave us the information we need. Is it too late to take him now I’m going to college and I really need the money. He’s not struggling either he’s a mechanic making $40 an hour and has never gave my mom a penny to help with me.
