Lvbssplyr, if I understand you correctly you are describing the nozzle which serves two purposes.
#1 it directs air from the piston (Which of course is the device which compresses the air) into the barrel behind the bb.
#2 it pushes one bb at a time into the barrel. (In this capacity, think of the nozzle as a bolt that cycles back and forth pushing the next round into the chamber).
Now, if the gun is not firing there are many different possible causes.
First, make sure the battery is fully charged, if it is, then try to focus on sounds. I wouldn't recommend connecting the charged battery and trying to "Push through it". In my experience this will really do you no good and in many cases actually exacerbates the problem.
If the issue is more than a simple bb jam or dead bat, it is likely that your gearbox is in trouble.
While, it is possible that the problem lies in a faulty electrical contact my guess is that you have heard a "Grunt" or a "Squeal" when you pulled the trigger. If you have, then its possible that the gears themselves have completely fallen out of allignment. That is, it is possible for the pin(s) on which the gears rotate to have worked themselves out of the frame of the gear box. This is basically like having the axle on your car slide horizontally out to the left or right. This results in the gear coming out of alignment and jamming the other two gears.
The first thing I would do is become VERY familiar with the names of the different types of internals. YOu will need to know the terminology to understand the guides on how to diagnose and fix the problems. (I.e. bevel gear, spur gear, sector gear, tappet plate etc...)
There are many online diagrams that will help (Java animations).
AS-R has some good stuff and here is a link to get you started.http://www.airsoftretreat.com/gallery/showphoto.php?photo=1336
For a good guide on how to take down an airsoft gun, DEFINITELY check out Mechbox.com @ http://www.mechbox.com/site/
. THis guy has really well done, detailed video guides on pretty much everything you need to know!
I would STRONGLY recommend that if you decide to disassemble your gun, watch the videos through completely at least twice AND make sure you do your disassembly in a wide clear area on something you don't mind getting dirty, but that has nice contrast. (YOU WILL HAVE LOTS OF LITTLE PIECES THAT HAVE WAYS OF DISAPPEARING).
Also, I would recommend getting a volt meter (Your local Radioshack should have one for less than $20). THis is an invaluable tool and it will help you determine if you have bad wiring, battery etc...
