Pre-check the fuel pressure in the fuel supply system as follows.
1. Check the serviceability of the fuel pressure regulator (see "Checking and replacing the fuel pressure regulator").
2. If the pressure in the system is less than 250 kPa (2.5 kgf/cm²), replace the fuel filter (see "Replacing the fuel filter").
3. If this does not help, remove the pump and wash the fuel receiver screen. If the pressure does not increase in this case, the fuel pump must be replaced.
You will need a flat-blade screwdriver.
1. Reduce the pressure in the fuel system (see "Lower pressure in the fuel system").
2. Disconnect the wire from the negative terminal of the battery.
3. Remove the rear seat cushion (see "Removing and installing the rear seat").
4. Use a screwdriver to pry...
5. ...and remove the plastic hatch cover.
6. Release the retainer and disconnect the wiring harness connector from the fuel pump module.
7. Disconnect the high-pressure fuel line tips from the pump fittings...
8. ...and the fuel drain line.
9. Unscrew the fuel pump module retaining ring by installing the pliers handles and lever as shown in the photo...
10. ...and remove the ring.
11. Carefully remove the fuel pump module and drain the fuel from it into a previously prepared container.
12. Remove the sealing gasket.
Note: Be sure to replace the gasket if it is torn or severely compressed.
13. Disconnect the fuel level sensor connector.
14. Squeeze the plastic clips and remove the fuel pump assembly from the collection cup.
15. Remove the fuel intake filter from the pump.
16. Use a screwdriver to press the fasteners and remove the upper part of the fuel pump assembly...
17. ... having disconnected the wiring blocks from the pump.
18. Remove the pump from the module housing.
19. Disconnect the fuel hose from the pump.
20. Assemble the fuel pump module in the reverse order of disassembly.
21. Install the parts in the reverse order of removal.
Note: When installing the module, make sure that the marks on the fuel tank and the module body match.
