2012 2500HD 6.0 Fuel Pump Control Module Location
I'd like to know if you can hear the fuel pump before starting the car when it works properly.
Then, I'd like to know if you can hear the fuel pump before starting the car when it refuses to start.
For each:
1. Turn ignition on to [Run] but not [Start]
2. Hear the fuel pump run
3. Turn to start to crank engine
Apologies for being so specific. Part of the joy of not knowing you and your skill level, and diagnosing from the far side of the Internet.

When it is working properly you can hear it before starting. When it’* not starting you can’t hear the pump. I have checked all the fuses and relays and even replaced the fuel pump relay just as a precaution. Starting to think maybe I have a malfunctioning control module that’* eventually frying the pumps over time?
