Is cranking but it will not start on 1998 Toyota Corolla

Is just cranking over and over but it will not start. But I found a relay in the engine compartment fuse box that was making a clicking sound. It was very dirty and brown I try to clean it with an electronic cleaner but it didn't clean it too good.

Were you able to find the solution to the no start problem? Was it the clicking relay? Or the starter motor?
