Starter just clicks once

Ok, I’ve had this starting problem for a long time. When I turn the key it just clicks once and nothing. I have changed the starter, the alternator. the ignition, because it would turn with out a key (which lead to it being stolen about 6 months ago, the ignition switch the dimmer switch(high beam, low beam switch) because it was not working any more, the turn signal switch, tried running a wire (purple wire) with the correct gauge straight from the battery to the solenoid and that worked, once. When I changed the starter, that worked once as well. I also got a new battery. What else could it be? Oh, I changed all the fuses too. I also replaced the battery cables. added 2 grounds as there was only 1 going to the frame, so I added 1 to the engine and 1 to the body.

This just started one day I was driving turned it off and then the click thing, what’s weird is a guy jumped me with good cables and it started, that’s when I figured the battery was bad and replaced it. Started once then back to click, replaced starter worked once, back to click. Had the old starter tested, it was fine. Also when I turned the key to on, the speedometer would jump to 50-90MPH before turning it to start. I even tried not hooking up the small wire going to the starter and jumped straight from the battery, click. Do I need a starter shim? It didn’t have one before. What is the other terminal for on the starter? One says S and the other B, I think.

One hard click is a starter(solenoid) or connection problem. Several clicks(click, click, click…) is a battery problem. If you are installing a remanufactured starter from like a1 cardone, toss it. Get a NEW starter.  the starter may test OK, but it obviously isn’t.  The “S” terminal is how the ignition switch activates the starter solenoid. It is working or you wouldn’t hear the click.  As this is a Chevy, one thing to look at would be the cables and cable connections at the starter to make sure they are not touching anything it shouldn’t or rubbed through at the block.

The most common reason for 1 click with all good connections, is the STARTER.
