Solution

1. Preparation

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

2. Battery Inspection and Replacement (if necessary)

Check battery voltage:
- Use a multimeter to measure voltage. A healthy battery should read around 12.6 volts.
Replace battery:
- If voltage is low, disconnect the negative terminal first, then the positive terminal.
- Remove the old battery and install the new one, connecting the positive terminal followed by the negative terminal.
- Torque the battery terminals to the manufacturer's specifications (typically around 10-15 ft-lbs).

3. Fuel System Inspection

Check fuel pump operation:
- Turn the ignition key to the "ON" position without starting the engine; listen for the fuel pump priming sound.
Replace fuel pump (if faulty):
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the negative battery terminal.
- Remove the fuel tank as per the vehicle service manual, disconnecting fuel lines and electrical connectors.
- Replace the fuel pump, ensuring proper alignment and connection of the fuel lines.
- Reinstall the fuel tank and reconnect the battery.

4. Ignition System Inspection

Check spark plugs and coils:
- Remove the spark plugs using a socket wrench; inspect for wear or carbon buildup.
- Replace spark plugs if worn (typically gap to 0.043 inches).
- Test ignition coils with a multimeter; replace any faulty coils.

5. Vacuum Leak Repair

Inspect intake manifold and hoses:
- Visually check for cracks or loose connections in vacuum hoses.
- Use a smoke machine or spray carburetor cleaner around the intake to check for leaks.
Replace any damaged hoses or seals.
