No spark

Hi, I recently came across a 1986 c10 with a 305 it looks in pretty good shape and interior is really good. He says it has no spark, he put in good used distributor, new cap and rotor, new coil, new fuel pump too. Still no spark. I was wondering if it would cost much to get it going? Maybe you guys would help me out? He said it just quit and would not start the next day. It for sure has no spark he just checked.
