Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Pump Fuse/Relay

Tools Required: Multimeter, fuse puller
Locate the fuse box (usually under the dashboard or in the engine compartment).
Use the multimeter to check the continuity of the fuel pump fuse.
If the fuse is blown, replace it with one of the same amperage.
Check the relay by switching it with a similar relay in the fuse box to test if it functions.

3. Check and Replace Fuel Pump (if necessary)

Tools Required: Socket set, fuel line disconnect tool, safety glasses
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines using the fuel line disconnect tool.
Remove the fuel pump assembly from the tank by unscrewing the retaining ring.
Install the new fuel pump assembly, ensuring all seals are replaced.
Reconnect the fuel lines and reinstall the fuel pump relay.

4. Inspect and Address EVAP System Issues

Tools Required: EVAP smoke machine (if applicable)
Visually inspect the EVAP canister and hoses for cracks or disconnections.
If available, use an EVAP smoke machine to check for leaks in the system.
Replace any faulty components discovered during inspection.
