  Q: How to remove and replace a fuel pump/sending unit assembly on Toyota Corolla?

  A: Relieve the fuel system pressure, then disconnect the cable from the negative terminal of the battery. Remove the fuel tank cap. Disconnect the cable from the negative terminal of the battery. Remove the rear seat from inside the passenger compartment. Remove the fuel pump/sending unit access cover. Unplug the electrical connectors, then disconnect the fuel lines. On 2005 and later models, the quick-release fitting on the pressure line can be squeezed by hand, without pliers. On 2003 and 2004 models, remove the fuel pump/sending unit retaining screws and remove the mounting flange. In 2005 and later models, the fuel pump assembly is retained in the tank by a large screw-on ring. A special tool is available which makes loosening and tightening this ring very easy, but a large pair of water pump pliers will work. Carefully withdraw the fuel pump/fuel level sending unit assembly from the fuel tank. The components of the fuel pump assembly are modular and all attach to the main housing. Remove the plastic support on the bottom of the pump by releasing the clips with a screwdriver, then pull-off of the rubber isolator, the fuel sock filter clip, then the electrical connector. Withdraw the pump from the housing. Inspect the strainer for contamination. If it is dirty, replace it. Reassemble the fuel pump/sending unit in the reverse order of disassembly. Install the fuel pump/sending unit assembly in the fuel tank. Connect the fuel line and electrical connectors. The remainder of installation is the reverse of removal.

  Q: What are some general checks for a fuel pump on Toyota Corolla?

  A: Check the Fuel Tank and listen for the fuel pump's noise when the ignition is on. If silent, inspect the electrical circuit. To test fuel pump pressure, remove the fuel line after relieving system pressure. If not, the fuel filter, line, injectors, pressure regulator, or pump may be faulty. If the pump doesn't start, replace the EFI fuse if needed. Check the wiring from the fuse/relay box to the pump if the pump doesn't work but the relays are fine.
