My 1991 riviera won't start its not saying nothing and my fuel pump is not on

Remove battery NEGATIVE cable FIRST... Now remove the positive cable(s) and clean both of them until they shine on both sides... Now clean them again!... Put positive cables back on battery and tighten... Now clean negative cable, put it back on battery and tighten... Try to start engine... If that doesn't help... Try jump start.... It is imperative that ALL cables AND battery terminals are clean and shiny!!!
