Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock or shorts.

2. Inspect and Replace Fuel Pump

Tools Required: Socket set, fuel pressure gauge, replacement fuel pump.
Remove the rear seat or access panel to locate the fuel pump.
Disconnect the electrical connector from the fuel pump.
Use a socket set to remove the fuel pump retaining ring and lift the pump assembly out of the tank.
Inspect the old pump for signs of failure (wear, damage).
Install the new fuel pump into the tank, ensuring it is seated properly.
Reinstall the retaining ring and reconnect the electrical connector.

3. Repair Fuel Tank Leak

Tools Required: Fuel tank repair kit (if applicable), wrench set.
If a leak is found, drain the fuel tank using a siphon pump.
Clean the area around the leak and apply a fuel tank repair compound or replace the tank if the damage is significant.
Allow the compound to cure as per manufacturer's instructions.

4. Replace Fuel Gauge Sensor

Tools Required: Socket set, replacement fuel gauge sensor.
If the gauge is inaccurate, remove the fuel pump assembly again (as described in Step 2).
Disconnect the fuel gauge sensor from the pump assembly.
