how to fix my Toyota Camry that won't start and just clicks?

Solution

1. Preparation

• Gather tools: multimeter, socket set, wrench set, screwdriver, battery terminal cleaner, safety goggles, gloves.
• Ensure the vehicle is in park (or neutral) and the ignition is off.
• Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

1. Clean Battery Terminals

   • Use a battery terminal cleaner to remove corrosion from the battery terminals.
   • Tighten any loose connections to ensure a secure fit.

2. Test Battery

   • Reconnect the battery and test the voltage again. If below 12.4 volts, consider charging or replacing the battery.

3. Replace Battery (if necessary)

   • If the battery is faulty, remove the old battery (unbolt and lift out).
   • Install the new battery, ensuring correct polarity (positive terminal first).
   • Tighten the battery terminals securely.

3. Starter Inspection

1. Locate the Starter

   • Refer to the vehicle manual for the starter's location; typically found near the engine mount.

2. Check Connections

   • Inspect wiring for frays or loose connections on the starter.

3. Test Starter Motor

   • Use a multimeter to test for voltage at the starter terminal while someone attempts to start the vehicle.
   • If no voltage is present, the starter may be defective.

4. Replace Starter (if necessary)

   • Disconnect the power and ground cables from the starter.
   • Remove the starter mounting bolts and carefully extract the starter from its housing.
   • Install the new starter, ensuring all connections are tight and secure.
