94 suburban won't start

I parked my 94 suburban about 2 weeks ago and used the battery out of it in a caprice. now the caprice is down so we switched the battery back into the suburban. but it won't do anything. the gauges, radio, all the electrics work, but it won't even try to crank. took the battery to walmart, it tested fine. but we do not get anything when turning the key. HELP PLEASE!

Gotta be bad cable connections, it seems.

Thank you for the quick help. I went and checked the cable connections coming off the battery, but they are fine. Do you have any other ideas on this. The truck was running and starting fine when i parked it.

is the ground good? if it is it might be your starter. do you hear a clicking or anything? if you dont even hear a clicking, i think its your starter..if you hear it, your batterys too weak. (usually)

try the pick up coil under the rotor...i just swapped mine
