Question moved to model category.

Did you disconnect the battery when you changed the starter over? Then did you reset the alarm and engine immobilizer?

Weak or bad battery, bad starter or poor connections or corrosion at the battery and or the starter.

If your 2007 Chevy Impala is making a clicking noise before the key is even inserted into the ignition, it could be caused by a few different issues. Some potential causes include:

1. Faulty starter motor: The starter motor is responsible for starting the engine when the ignition is turned on. If the starter motor is faulty or has worn out, it may make a clicking noise as it tries to engage with the flywheel.
2. Loose or damaged starter motor relay: The starter motor relay is an electrical component that sends power to the starter motor when the ignition is turned on. If the relay is loose or damaged, it may cause a clicking noise.
3. Low battery: If the battery is low on charge or has gone bad, it may not have enough power to start the engine, causing a clicking noise.
4. Other electrical issues: There may be other electrical issues, such as a loose connection or a problem with the ignition switch, that are causing the clicking noise.

To determine the cause of the clicking noise, it is recommended to bring your vehicle to a mechanic or a dealership for further diagnosis and repair. They will be able to test the starter motor, battery, and other electrical components to determine the source of the problem and recommend the appropriate repairs.

Question edited for clarity and a bit of punctuation.

Get underneath the Mazda and put put charger leads on the red terminal of the starter motor, and the negative on any good ground. BUT the keys are in the Impala so you have to start there!

Maybe a bad starter?

simple stuff 1st

1. Check the battery for volts. You can have your lights but not enough to start. should read 12 or more volts. if not remove battery cables from posts clean posts back to silver color all the way around and charge.
2. Clean the cables where they connect to posts till silver. Wire brush or file it
3. reconnect and make sure there tight and try start
4. if no start follow the battery cables and clean and tighten at starter and ground to frame.
5. Try start
6. no start then test solenoid and bench test starter.

Hope this helps Mike

my be the alternator - mine went out and all the gauges and stuff quit working had to have it jumped twice to get it back to parts store so I could change alternator - may want to have that checked!!

Low or dead battery most likely, use this procedure to trouble shoot the system:
READ THIS ALL BEFORE YOU DO ANYTHING
NOTE: some vehicles have the starter relay and starter mounted together as 1 unit. Sometimes the starter relay and starter are seperate. When I refer to "relay" it could also mean the starter and relay as 1 unit.
Note: "starter switch" is not to be confused with "key switch", although sometimes they are all one unit. The starter switch is usually mounted on the steering column and actuated by a metal rod. On units that are all one unit, the keyswitch/starter switch (both one unit) will have to be replaced. (this is a rare problem, so don't get worried just yet)
1. Check battery voltage, should be between 12.5-14.5 volts. if low voltage replace or charge battery, and try to start car, if it don't crank with new or charged battery, move on.
2. Check connections on the starter relay, even the small one coming from your starter switch. if loose or corroded, clean with a brush and reconnect them. Try to start your car. Did it start? if not, Move on
3. Well now we know the connections aren't the problem. How about a click? did you hear one? If a click is heard, go to #4, if nothing is heard, go to #5
4. Well at least the relay is clicking, but nothing else is going on. The relay is working, so the starter must be bad. Replace the starter and start your car!
5. Humm, connections aren't the problem, maybe the relay is bad, replace your relay with a new one. Move on
6. Now we have a new relay, with clean and tight connections. Start your car. Does it start? If yes, then HORRAY! we fixed it. Does it click? If so then goto #7, If it don't click, then goto #8
7. So here we have a new relay, with good connections that will click when trying to start the car, but nothing else happens. Starter is faulty, replace the starter, and off you go, see ya!
8. So here we have a new relay, with good connections, but it still won't click when we try to start our car. This means that your starter switch is faulty. Replace starter switch and try to start your car. Vroom! finally done with this car problem!
List of shortcuts: if you remove the starter switch lead (small wire) from the relay and apply +12v to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. You can actually hook up a starter button this way. If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken.

Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection.
Problem is most likely the Solenoid or starting relay, whichever the car uses.
Hope this helps.

if the starter spins but does not engage flywheel. then its the starter solinoid thats bad. its on top of starter, when key is turned to start, the solinoid is activated, and it pushes the gears out to make contact with flywheel to start vehicle. so the solinoid just spins with out kicking out to flywheel. change solinoid or get another starter. have a good day !

The starter motor on a car takes a lot of energy, you may be able to use the radio but not have enough power for the starter. You also might not be able to start it because the motor's starter or it's relay is bad. So here's what to do:

Check the connections on the battery, try loosening the connections and moving them around a bit, then tighten them down good.

Next go try to start it up again. If it still doesn't respond, turn your headlights on and see if they are still bright. If they are, then I would look into the starter or the starter relay.

The relay is in a box somewhere under your hood, possibly with some motor related fuses. Take the cover off and look at the under side of it. The cover should have a sticker displaying which relays do what. Now look for the air conditioner relay. Check to see if the air conditioner and starter relays have the same number printed or stamped on them. ONLY if the numbers mach, put the air conditioner relay in place of the starter relay, and try to start it again.

If you still get nothing, then it is either a bad starter or wire somewhere. On this car it may be a bit difficult to find and reach, but try to get to the starter on the bottom of the car. You can find pictures online of what it looks like if you are not sure. Play with the wires and knock on the starter with something hard like a rock or hammer. It doesn't take too much to do it, even a firm punch can do it, just don't break it. If this works then the starter is bad and needs serviced or replaced.

If there is still no response after this, there is nothing more you can do unless you are capable of taking things apart and checking the wiring. Good luck!
