* Weak or dead battery: This is the most frequent cause. A battery that can't supply sufficient amperage will produce a clicking sound from the solenoid as it tries to engage, but fails due to lack of power. Have the battery tested at an auto parts store.
* Corroded battery terminals or cables: Corrosion restricts current flow. Clean the terminals and cables with a wire brush and baking soda solution.
* Faulty starter motor: The starter motor itself could be failing internally. While less common than a bad battery or cables, internal damage can prevent it from drawing enough current to crank. This often manifests as a weak click rather than a strong one.
* Poor connections in the starting circuit: Check all the connections between the battery, solenoid, starter motor, and ignition switch. Loose, corroded, or damaged connections can interrupt the electrical flow.
* Ignition switch problem: A faulty ignition switch may not be sending the correct signal or enough power to engage the starter.
* Neutral safety switch (automatic transmission): If your Tempo has an automatic transmission, this switch prevents starting unless the gear selector is in Park or Neutral. A faulty switch can prevent the starter from engaging.
* Wiring problems: A break or short in the wiring between any of the components mentioned above can also cause clicking.
Troubleshooting Steps:
1. Check the battery: This is the *first* thing to do. Test voltage and load test the battery.
2. Inspect battery terminals and cables: Clean them thoroughly.
3. Listen closely to the click: A weak click often points to a low battery or a failing starter motor. A strong click followed by nothing usually points to the starter motor itself.
4. Check all connections: Visually inspect all connections in the starting circuit for corrosion, looseness, or damage.
5. Have a professional diagnose it: If you're not comfortable troubleshooting electrical systems, take your car to a mechanic for a proper diagnosis. They have the tools and expertise to pinpoint the exact problem.
Remember safety first. Disconnect the negative battery terminal before working on any electrical components.
