97 PSD F-250 won't start
 

Hi everyone,

I have a 97 F-250 PSD. I woke up and tried to start it in the morning and it just spun. then the battery died. I get codes

p0344 & p0562. bad cps, and low voltage. I had a spare cps, installed it, charged the battery, no start. the # 22 fuse looks fine, but I'm on my way to the store to buy a replacement jic.

what should I be doing now? I have my battery charger hooked up, as well as the block heater.

Thanks!
