my Toyota Camry won't start but has power what should I check

Solution

1. Preparation

• Gather tools: multimeter, socket set, screwdriver, and safety gloves.
• Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Inspect and Clean Battery Connections

• Disconnect the negative battery terminal first, followed by the positive terminal.
• Clean the terminals and cable ends with a wire brush to remove corrosion.
• Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

3. Test and Replace the Starter Relay

• Locate the starter relay in the fuse box based on the owner's manual.
• Remove the relay and test it using a multimeter for continuity.
• If faulty, replace it with a new relay of the same specifications.

4. Check and Replace the Starter

• If the starter relay is functioning, proceed to inspect the starter.
• Disconnect the battery again.
• Remove the starter by unbolting it from the engine block and disconnecting the electrical connectors.
• Inspect the starter for signs of wear or damage; if defective, replace it with a new starter.
• Reinstall the starter, ensuring all connections are secure.

5. Verify Ignition Switch

• If the starter is not the issue, check the ignition switch.
• Remove the steering column covers to access the ignition switch.
• Test for continuity with a multimeter when the key is turned to the start position.
• Replace the ignition switch if it does not show continuity.
