Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, screwdrivers, safety goggles, gloves.
Disconnect the negative terminal of the battery to ensure safety during the repair process.

2. Fuel Pump Replacement

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Remove the rear seat or access panel to locate the fuel pump module.
3. Disconnect the electrical connector and fuel lines from the fuel pump module. Be cautious of any residual fuel.
4. Unbolt the fuel pump module from the tank and remove it.
5. Install the new fuel pump by reversing the removal steps and ensure all connections are secure.
6. Reconnect the battery and test the system by turning the ignition on (do not start) to prime the fuel system.

3. Fuel Injector Cleaning/Replacement

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the engine cover (if applicable) to access the fuel rail.
3. Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
4. Detach the fuel lines and electrical connectors from the fuel injectors.
5. Remove the fuel rail with the injectors attached and extract the injectors from the rail.
6. Clean the injectors using a specialized injector cleaner kit or replace them with new units if they are damaged.
7. Reassemble the fuel rail and reconnect all lines and connectors.
