• Q: How to remove the fuel injector on 2008 Toyota Prius?

  A: The first step to remove a 1NZ-FXE fuel injector requires users to discharge fuel system pressure by removing the integration relay from the engine room junction block and following the specified procedure to disable engine start. Before reinstalling the integration relay it is necessary to remove the fuel tank cap for air release while disconnecting the negative (-) battery terminal cable and waiting for at least 90 seconds to prevent Air Bag and seat belt pretensioner activation. The service begins by detaching the windshield wiper motor and link followed by disconnecting the No. 2 engine room relay block to extract the front outer cowl top panel sub-assembly including all wire harness clamps and bolts and air cleaner assembly and brake master cylinder reservoir sub-assembly by removing the brake fluid level switch connector and associated bolts and claw fitting. Detach the reservoir bracket by removing the No. 2 fuel vapor feed hose with its connector clamp as well as the wire harness clamp and bolts. The next step involves removing the cylinder head cover sub-assembly after wire harness clamps have been taken off and fuel injector and ignition coil connectors have been detached and all bolts alongside the engine wire and brake master cylinder reservoir cover have been removed. Pull out the ventilation hoses after which you can remove the cylinder head cover. The fuel tube requires disconnection from the delivery pipe by undoing the No. 1 fuel pipe clamp and extracting the fuel tube connector without tools to avoid scratches or foreign objects. Following bolt removal from the fuel delivery pipe you should unload its 4 fuel injectors with caution before extracting the No. 1 delivery pipe spacers and insulators from the cylinder head. Pull out the 4 fuel injectors from the fuel delivery pipe as the final procedure.
