Solution

1. Preparation

Gather all tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Tools Required: Multimeter, wrench set, battery terminal cleaner.
Disconnect the negative battery terminal first, then the positive.
Use the multimeter to check battery voltage; replace the battery if it reads below 12.4 volts.
Clean the battery terminals with a terminal cleaner.
Reconnect the battery, connecting the positive terminal first, followed by the negative.

3. Fuel System Check

Tools Required: Fuel pressure gauge, screwdrivers, safety goggles.
Locate the fuel rail and connect the fuel pressure gauge to the test port.
Turn the ignition to the ON position (do not start) and check the pressure against manufacturer specifications.
If the pressure is low, inspect the fuel pump and replace if necessary.

4. Ignition System Inspection

Tools Required: Socket set, torque wrench.
Remove the spark plugs using the socket set and inspect for wear or fouling.
Replace spark plugs if they are worn, ensuring to gap them to manufacturer specifications.
Check ignition coils for proper operation; replace any faulty coils.

5. Verify Fuel Delivery

Tools Required: Inspection tools, miscellaneous hand tools.
Inspect fuel lines for leaks or cracks; replace any damaged sections.
Ensure the fuel filter is not clogged; replace if it has not been changed per service intervals.
