Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shock.
Tools required: OBD-II scanner, multimeter, fuel pressure gauge, socket set.

2. Inspect and Replace Battery

Check Battery Voltage: Use a multimeter to check voltage; it should be above 12.4 volts.
Clean Connections: Remove corrosion from battery terminals using a wire brush.
Replace Battery: If the battery is weak or old (over 3-5 years), replace it with a new, fully charged battery.

3. Test and Replace Fuel Pump

Check Fuel Pressure: Attach the fuel pressure gauge to the fuel rail; ensure it meets manufacturer specifications (usually between 50-60 psi).
Listen for Pump Operation: Turn the ignition to the ON position (do not start), listen for the fuel pump priming sound.
Replace Fuel Pump: If the pressure is below specifications or the pump does not activate, replace the fuel pump.

4. Inspect and Replace Spark Plugs

Remove Spark Plugs: Use a socket set to remove the spark plugs.
Inspect Condition: Check for wear, carbon buildup, or damage.
Replace as Necessary: Install new spark plugs according to manufacturer specifications (usually gap 0.054 inches).

5. Clean or Replace Fuel Injectors

Remove Fuel Injectors: Take out the fuel rail and injectors carefully.
Clean or Replace: Use an injector cleaner or replace if they are clogged or damaged.
Reinstall Components: Ensure all seals are replaced and components are reattached properly.
