You don't have throttle body injection; you have sequential port fuel injection that's located under the intake manifold. It has poppet valves (one for each cylinder) and a fuel pressure regulator as a unit (kinda looks like a spider, hence the name).

I don't know what the fuel pressure is supposed to be on an '01, but it's something like 62 psi...but don't quote me on that.
