Wrench Buzzing noise in throttle body

Okay.. I have posted several threads on my 2002 Saturn l300 v6 3.0
The other day my boyfriend cleaned out the throttle body it was filled with oil and dirt. He put the throttle body back on hoping thatís the reason why it is cranking but not starting...battery was almost dead from trying to start the car. The car fired up but only last a few seconds before shutting off. Tried again tonight with almost turning over but not completely. We are hearing a ringing noise coming from the throttle body, we think it may be the sensor? But are not for sure. We did not know that the car may start but will not drive if we unplug the throttle body. When he put the car in the run position I did not see the throttle body flap open at all and when he unplugged the throttle the ringing sound went off. Does this mean I need a new sensor? I also called autozone but they said I would have to replace the throttle body itself it doesnít come with just the sensor itís the whole assembly is that true? Any help is so much appreciated!

REWARD EXCELLENCE!

When the gas pedal is pressed, does the throttle plate respond?

Iím not sure what the high code is? And the battery is dead and itís hard to keep the battery charged when trying to turn on the car to start it. The things that we see are car cranks but no start, ringing sound from the throttle bottle, when gas pedal pushed the throttle pedal does not open and we do not hear the fuel pump humming.
