I have a problem.. It is an 04 ES330 model.. I was doing the EFI managment on the car.. After the efi done, I was unplug the fuel line from EFI off the fuel rail and the gas starting to flow out.. I get the fuel plug back to fuel rail and then the fuel stop flowing.. I then started up the car and the car went start smooth.. Something was going on.. The fuel needle dont go back to where it was.. I installed the fuel sender from the fuel pump.. It wasnt the answer.. Then I checked the fuse and the fuse look fine.. What can I do? HOw can the gas needle work?
