Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is in a well-ventilated area and on a flat surface.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Battery Inspection
  • Tools Required: Multimeter, wrench set.
  • Inspect the battery terminals for corrosion; clean if necessary.
  • Measure the battery voltage with a multimeter. If the voltage is low, charge or replace the battery.
  • Reconnect the battery terminals securely.
3. Starter Check
  • Tools Required: Multimeter, screwdriver, ratchet set.
  • Locate the starter motor, typically found near the engine's transmission.
  • Measure voltage at the starter terminal while someone turns the ignition key to the start position. If no voltage is present, proceed to check the ignition switch and wiring.
  • If voltage is present but the starter does not engage, replace the starter motor.
4. Relay and Fuse Replacement
  • Tools Required: Fuse puller, screwdriver.
  • Locate the fuse box and identify the starter relay and ignition fuses.
  • Replace any blown fuses with the same amperage.
  • Swap the starter relay with another identical relay from the fuse box to confirm if the relay is faulty.
