If its not turning the engine over very fast or at all and that is the description of just one click. You turn the key and nothing but a click without the engine turning over is Bad Battery, Battery Terminals Bad one or both, Bad Starter, or connections to those. Doubtful but I will list to cover everything, Ignition switch, fuses. Since you did a new battery, I would check the terminal wires then do the starter replacement. If the terminal wires are old 1991 wires replace these as they could never be as good as they need to be. If it still just clicks replace starter. Keep the receipts for all parts.
