Hehe, ok. What I think is going to help you the most is a Toyota Factory Service Manual. You can download what you need from here
Toyota Tacoma/ 4Runner/ Tundra/ FJ Cruiser Factory Service Manual Page
It looks like you are going to need to test your sending unit per the FSM, it also has a troubleshooting section that will help you dial in where the problem lies if it is not at the sender.. It sounds like you have a multimeter and know how to use it, so now all you need are the resistance values for the sensor(s) and you are set.
