Question about 2003 Chevrolet Tahoe
Changed batterty, alternator, etc, but after it sits for two or three days it will not start
Why change battery and alt? Both failed together, not likely. Clicking of the starter solenoid has for decades been a battery gone bad or a starter issue. Solenoid or starter motor brushes etc. What relationship has the sitting and not starting have to do with it. The alt only keeps the battery charged if it the alt can not supply the current needed to run the veh and draws on the battery. That battery keeps the computer memories live and turns the starter over. New battery. Are all the ground wires clean and tight? There may be Relays for the starting circuit. Please do not throw parts at it. Take it to the very best, close by repair facility or dealer. These vehicles are very complex today and even with my 45 years experience,some professional we can't keep up.
