Talking 2005 C5500 LLY help

2005 GMC C5500 throwing a code P0193. Changed the fuel Rail Pressure Sensor. No Luck. Do I need to replace the FICM? and is there any way to know if the unit is good or bad

Moved into LLY section. The "attn newbies" thread isnt for tech questions.

Yeah worm what Tom said. 0193 is a fuel temp code isn’t it? Mine showed that code quite a bit when the injectors were returning too much fuel. A race plug and a lift pump fixed the code though and brought rail pressure from 13k to 19k lol.
