Solution

1. Preparation

Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set
Check the battery voltage with a multimeter; it should read around 12.6V or higher. If the voltage is below 12.4V, charge or replace the battery.
Inspect battery terminals for corrosion. Clean them with a mixture of baking soda and water if corroded.
Reconnect the battery and secure the terminals.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge
Check the fuel level in the tank; ensure it is above a quarter tank.
Attach a fuel pressure gauge to the fuel rail to check for adequate fuel pressure (refer to manufacturer specifications, typically around 30-40 psi).
If pressure is low, inspect the fuel pump relay and fuel filter for blockages or faults.

4. Ignition System Check

Tools Required: Socket set, spark plug socket
Remove spark plugs and inspect for wear or fouling; replace if necessary.
Test each ignition coil using a multimeter to ensure they are functioning properly (refer to specifications for resistance values).
Replace any faulty ignition components.

5. Starter Motor Functionality

Tools Required: Multimeter, socket set
Inspect starter motor connections for tightness and corrosion.
Perform a voltage drop test on the starter motor circuit to ensure proper operation.
If the starter motor is faulty, remove it using a socket set and replace it with a new starter.
