Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection and Replacement (if necessary)

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Inspect the battery for swelling or leakage; replace if damaged.
3. Clean the battery terminals with a wire brush and baking soda solution.
4. Reinstall the battery (positive first, then negative).
5. Ensure all connections are tight.

3. Fuel System Check

Sub-steps:
1. If fuel pressure is low, replace the fuel filter and inspect the fuel lines for blockages.
2. If the fuel pump is faulty, replace it by removing the rear seat to access the fuel pump assembly.
3. Ensure all electrical connectors to the fuel pump are secure and free of corrosion.

4. Inspect and Repair Vacuum Leaks

Sub-steps:
1. Visually inspect hoses connected to the intake manifold for cracks or disconnections.
2. Use a smoke machine to detect any vacuum leaks.
3. Replace damaged hoses as necessary and ensure all connections are secure.

5. Final Reassembly

Sub-steps:
1. Reconnect the negative battery terminal.
2. Ensure all tools are removed from the engine bay.
3. Start the engine and allow it to idle to check for any irregularities.
