Broken Scion might be rising from the dead!

[xmodificationer]

i was going to do a 6 cell in my PN scion, so instead of putting it in there first i decided to try it on my returned scion to make sure i know how to do it right. well i got it on the returned but i decided to take out the whole EP for no reason then i soldered back on all the wires and stuff and i turned it on and it centered the steering! it wouldnt do that when i first got it, but i try to steer and make it go with the controller and nothing happens. so whats the problem? why wont it steer or go? well heres a pic of the chassis it didnt look like there was anything fried though so idk waht to do now.
