Does the fuse on the positive battery cable have to be there for car to start or run right

What is your question?

The only way my car will start is with a jump. Battery tests good,put a new starter on still same problem, put a new alternator and new belt on still have same problem. I was wondering if that fuse on the positive cable have to be there becasuse it broke would that or could that be why My car will not start on its own?

What makes this problem better or worse?

Jump is the only way I can start my car
