Truck won't start

2000 Dodge Ram 1500 mileage:110000 engine size 5.9L V8

The truck got home fine. No noise or dash lights. Nothing out of the ordinary. The next day it wouldn't start. Checked the battery and it's ok.

Pulled the starter. Had it checked. It passed, but the guys at the parts store said it "sounded weak." I tried 2 different new starters and it still wouldn't start. When I turn the key, I hear clicking and buzzing as the truck gets ready to start, yet nothing happens outside of that. I switched the relay from the blower with the starter relay and still nothing.

What do I do now? I put the old starter back on since the others didn't get me going.

Thanks
