Sounds like you might have what's called a parasitic draw on your battery. Parasitic draw is an electrical component staying on after you turn the car off (that isn't supposed to be staying on) and draining the battery over night. This can be caused by a multitude of things- the light in the glovebox staying on, an aftermarket accessory incorrectly installed to your vehicle, or malfunctioning, a factory component in the car malfunctioning and staying on, a power seat switch stuck on... the list goes on and on. The easiest things to check would be your dome lights, trunk lights, sun visor lights, glove box lights, and seat switches. Make sure the lights are all off after you take the key out and close the doors. Make sure none of the power seat switches are stuck on. If you can't find anything checking the lights and seats, you're going to need a digital multimeter connected to the battery to measure amps, to measure the actual parasitic draw. Once you establish how much parasitic draw there is (30 MilliAmps or less is acceptable), you're going to need to start pulling fuses one at a time to find out where the parasitic draw is coming from. When you pull a fuse and the parasitic draw on the meter goes away, you've isolated the circuit. Then you'll need to find what on that circuit is using power when it shouldn't be.
Good Luck :)

SOURCE: 1990 Lincoln-Battery drained while turned off sitting

If you are jumpering the starter, then the battery is not being drained, the starter may have a bad solenoid.
If the problem still is a dead short, a painstaking troubleshooting is required.
Remove one fuse at a time, check for voltage drop, and see which one is the culprit. Then you woud have to locate each item on that circuit and trace the wires for one that is broken, or pinched & contacting ground.
Also, check at night or in a dark garage, as trunk, door, or hood pin switches may be stuck in the open position - and will keep the lights on.

Interesting note - your having to jumper the solenoid on the starter indicates a possible worn/damaged ignition tumbler. If your tumbler is not seating on the OFF detent, your ACC may still be left on even with the key out of the ignition.

SOURCE: car wouldnt start replace ignition switch, clutch switch then starter worked for 2 days now starter clicks but wont start left overnight car starter but when turned off wont restart

sounds like there is a dead spot in the starter. i think the other stuff may not have needed to be replaced. when the car won't start, have someone try to start while you TAP the starter with a hammer.- probably the starter, though.

Yes. the starter is malfunctioning at this time. it could also eb a ignition issue as well. here is a quick starter test procedure that will help you troubleshoot a bit.

Step 1 Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.

Step 2 Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.

Step 3 Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.

Step 4 Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.

Step 5 Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.

Have the vehicle scanned, I think you'll find that the coolant temp sender unit may be defective.Regards Johngee

I just replaced the starter in my car and it still just clicks what would my issue be

Check positive and ground cables first. Clean any corrosion, replace if it is bad. Could also have bought a bad,new starter.

Clicks when i try to start it, not the starter battery terminals or relay?

Then it is the cable from the battery to the starter. Corrosion will make it's way down inside the cable. Corrosion causes resistance. Too much resistance causes not enough voltage/amps to a particular part.

My 2002 Toyota Tundra 4.7(V8) has an intermittent start and the battery drains overnight from 12.5V to around 10.0V. I've tested for parasitic draw and every time I test my reading is ~ .025A...

I think I would attack the drain problem first. Something has to be draining the battery, it does not have to be a steady drain. It could be something serious for 30 min in the middle of the night. You may need to pull fuses one at a time to try to narrow down the circuit. it could even be a weak component in the alternator or computer. I know you said you replaced the alternator.
If it goes down overnight, it should also go down during the day. Can you leave the meter connected and check it every hour or so ? ?
Another component that could be suspect is the key switch. I know you said you checked it, but it could be a part-time problem.
When the starter or relay clicks, I would want to know how much voltage I have at the starter post, and coming out of the key switch. Then how much at each point in between. You also have a neutral safety switch in that circuit.

Car won't start without being charged and when it sits overnight it wont start. makes a clicking noise when trying to start it

Battery is to weak & not holding charge. If the battery does not have enough power the starter will make a fast clicking sound or you will just hear one click.

When I go to start my car, it just clicks and wont start. I have power (lights, interior lights, radio, etc.)

You have a bad starter,you can take it out & have it checked at autozone or any kind of auto parts store.

The starter only clicks and the battery is fully charged. won't start

The starter only clicks.This is indication of faulty starter or starter solenoid jammed.Check the connection between starter to battery.Remove the connections and recheck.If still the same problem then see if the starter is proper or faulty.Measure the voltage of starter by meter.Its a 12 volt part.If the voltage is low then its faulty starter or if the solenoid is jammed then also starter needs to be replaced.Check out this possibilities.This will help.As you mentioned that battery is good and properly charged as per this, the starter or starter connections to the battery seems faulty.Clean the battery to starter connections with carb cleaner.It can be available at any local car garage or at auto part store. -------- Thanks.Helpmech.

98 Buick LeSabre won't start. Battery and starter are both good. What else could it be?

Remove the battery terminals and clean them real well and tighten them back on the posts. If you have a bad connection here, you will get the problem you described. When you are done, go ahead and put your starter back in. While you are down there, check the voltage on the thick wire supplying battery voltage to the starter make sure it is 12V. Try to start the car and get back to me.
