Solution

1. Preparation

Gather tools and ensure safety equipment is available.
Disconnect the negative terminal of the battery to prevent sparks.
Allow the engine to cool and relieve fuel pressure from the system.

2. Inspect Fuel Lines

Tools Required: Socket set, wrench, safety glasses, gloves
Check the entire length of the fuel lines for cracks or leaks.

Tools Required: Jack and jack stands (if necessary), flashlight
Inspect the fuel tank for any visible damage or corrosion.
If a puncture or crack is found, remove the fuel tank by:
1. Supporting the tank with a jack.
2. Disconnecting the fuel lines, electrical connectors, and straps.
3. Lowering the tank carefully.
Repair the tank using a sealing compound or replace it if severely damaged.

4. Inspect Fuel Injectors and Rail

Tools Required: Wrench, rags, safety glasses
Remove the engine cover if applicable.
