Throttle body Issues

Turn on your headlights, dome light and watch the dome light as you turn the key to start. Sort of like using a twelve volt test light. First of all the light should be bright to begin with, if not, then you need to charge the battery. Then light should dim slightly when you turn the key to start and the starter should crank over, that would be normal.
If the light goes out completely and you get just one click from the starter and/or starter relay, then you have a loose electrical connection and could possibly be a loose battery terminal. If the light stays bright, the starter does nothing and not even a click, then you most likely have a blown fuse or a bad ignition switch or bad starter relay.
If the light dims heavy, almost out but still on very little, the starter maybe crank over really slow or maybe a clicking or even just the one click, then the battery is weak or drained and needs a charge, then check why it is low, either you was cranking over the engine too much and drained the battery down or there is a short circuit somewhere draining the battery over time. When cranking the starter over though, do not crank for longer than ten seconds if it does not start, stop cranking and allow the starter to cool down for ten seconds before trying again.
The fuse I see as #7 in the integrated power module, located under the hood left side just in case it might be the fuse.

I do not think the throttle body would directly affect the starter, only that maybe like you said continuing to try to crank the engine over and it not starting would eventually drain the battery though.
When you got the jump, did at least the starter crank the engine over fast enough?
I am not dealing with the throttle body issue right now, just the fact that the starter will not crank over.
