What is the problem you are having? What is the price difference between just the injector and the whole TB?

my truck is able to start fine, but for a while when it's sitting to warm up. it will just completely shut down like there isn't fuel anymore. it's either injector or someone put water in the tank.

the price for injector is $189.51 and $295.37. my supplier is maslack.com/automotive

Have you checked the fuel pressure? It is easy enough to tell if there is water in the fuel. Get a glass beaker and take some fuel from the tank and put in the beaker. Let it sit a while and you will be able to see if the water settles to the bottom (you could use something line a mason jar or just a drinking glass too).

Try putting soem "heet" in the fuel. I wouldn't change parts that don't need changing. If all else fails, just run the gas out of it and refill it with some known good gas.

You could check the pressure and see if it is within specs.
