Misitified

need some help here, i have an 01 went to gas station filled her up got back in car and one hard click and car wouldnt start. I assumed starter, tried banging on it with long extension and hammer while friend tried cranking car over, still nothing but one solid click. Towed vehicle home, ordered up a starter... installed new denso starter(same as oem) with same results just one solid click when I try to start her up. Bench tested both starters, both work great on bench. I checked my power wire to starter, it checks good, checked ground wire, it checks good, replaced both terminal ends on battery with oem, still same problem. Has anyone had similar problem? its not the starter or battery thinking of ordering up new power and ground wires for the starter and battery, maybe corroded? Ugh!! Need some help hopefully someone out there has had similar issue?
