My 91 Jimmy has an occasional starting malfunction. Checked battery and connections. But it still clicks once in awhile when I turn the key? Can i find a wiring diagram of the starter system?

Did you check and clean all battery connections? Make sure to also check and clean the negative connection on the frame and motor. Also check and clean the connections on the starter and sylnoid.
