Diagnostic Steps

1
Check the battery voltage using a multimeter; it should be above 12.4 volts.
2
Inspect battery terminals for corrosion and ensure they are securely connected.
3
Test the starter relay by swapping it with a similar relay in the fuse box.
4
Use an OBD-II scanner to check for any stored trouble codes that may indicate electrical issues.
5
Measure voltage at the starter solenoid with the ignition turned to the start position.

Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Check Voltage:
- Reconnect the multimeter to the battery terminals.
- If the voltage is below 12.4 volts, proceed to jump-start the vehicle or replace the battery if it does not hold a charge.
Clean Terminals:
- Disconnect the battery terminals.
- Clean any corrosion with a wire brush or terminal cleaner and reconnect securely.

3. Starter Relay and Solenoid Check

Relay Testing:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to see if the starting issue resolves.
Starter Solenoid Voltage Test:
- Reconnect the negative terminal and turn the key to the start position.
- Measure voltage at the starter solenoid. If voltage is present but the starter does not engage, replace the starter.

4. Starter Replacement (if necessary)

Remove Starter:
- Disconnect the battery again.
- Remove any components blocking access to the starter.
- Unbolt the starter from the engine block and disconnect the wiring harness.
Install New Starter:
- Position the new starter in place and secure it with bolts to the engine block.
- Reconnect the wiring harness to the new starter.

5. Final Reconnection

Reconnect the battery terminals.
Ensure all previously removed components are reinstalled correctly.
