Question

I have a 2004 Chrysler PT Cruiser with engine code P0129 and P0122, and engine won't start

Answer 1

p0129 is for the map sensor, I cant post more info on it since I dont know if you have the turbo'ed model or not 

you can try to check all the fuses since pt crusiers do have that issue.

you can also try to clean the parts with mass air flow sensor cleaners

and P0122 is for the throttle position sensor
