Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery and Connections Check

Step 1: Clean battery terminals with a wire brush if corroded.
Step 2: Tighten any loose connections.
Step 3: Reconnect the battery terminal and ensure a secure fit.

3. Fuel System Inspection

Step 1: Locate the fuel pump relay (in the power distribution box) and check for proper operation.
Step 2: If the relay is working, test the fuel pump by applying direct voltage to it.
Step 3: If the pump does not activate, replace the fuel pump assembly as necessary.

4. Ignition System Assessment

Step 1: Remove the ignition coil and inspect for damage.
Step 2: Test the ignition coil with a multimeter (specifications: primary resistance 0.5-2 ohms, secondary resistance 6,000-15,000 ohms).
Step 3: Replace any faulty ignition coils.

5. Starter Motor Check

Step 1: Locate the starter motor and inspect the wiring for damage.
Step 2: Test the starter motor by applying direct battery voltage to it.
Step 3: If it fails to engage, replace the starter motor.
