3. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (refer to the owner's manual for location).
Inspect fuses related to the starter and ignition systems for continuity.
Replace any blown fuses with the same amperage rating.

4. Test the Starter Motor

Tools Required: Multimeter, jumper cables
Connect the multimeter to the starter motor terminals.
Have an assistant turn the ignition key to the start position while you check for voltage at the starter.
If voltage is present but the starter does not engage, replace the starter motor.
