My car wont start ccx

My car wouldn't start at the gas station friday b4 last and I
finally got it to and drove home but my breaks were nearly
non existant and when I would press the brake i could hear
a strange noise almost like from the tire or maybe the brake
booster..  so I went to auto zone to get brake pads cuz they
were a but thin. I got to autozone made the purchase and
my car wouldn't start at all. I depleted my battery trying to..I
had to be towed home but 1st I had autozone scan it. It  
threw 3 codes.. p0014, p0017, p0556,
The brake booster has been changed,  as well as the
variable camshaft timing solenoid.  I also needed a new
battery I just put that in and it started immediately. I bleed
the brakes and then put the reservoir back on and out the
tires back on it and now it wont start. I put it I. Neutral to
safety start it and it started, I drove around the block to the
water hose turned it off and now it wont start in safety
either.. I really dont know what else to do...
