Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery (negative terminal) for safety.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean battery terminals using a wire brush to remove corrosion.
2. Tighten the battery terminals securely.
3. If the battery voltage is low (below 12.4 volts), replace the battery.
Tools Required: Wire brush, socket set.
Safety Warnings: Always wear safety goggles and gloves when handling batteries.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Remove the starter motor from the vehicle (typically requires removing battery, disconnecting wiring harness, and bolts).
2. Test the starter motor using a multimeter to check for continuity.
3. If faulty, install a new starter motor following the reverse order of removal.
Tools Required: Socket set, wrench set, multimeter.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and check for continuity.
2. If the relay is functional, check the fuel filter for clogs; replace if necessary.
3. Ensure proper fuel delivery by checking the fuel pressure using a fuel pressure gauge.
Tools Required: Fuel pressure gauge, socket set.
Safety Warnings: Relieve fuel system pressure before disconnecting fuel lines.
