1993 Nissan Maxima

My 1993 Nissan Maxima runs great but about every 3-6 weeks it refuses to start. Battery is charged. It does not even “click” when you turn the key on. Let it sit a couple hours and it starts right up until the next time it refuses to start

You may have a bad ground from the engine to the body. Find that wire, disconnect the body end and clean it with a wire brush or pochet knife. If tha does not work, change the starter or the negative battery wire.
