Question Fuel Pump Primary Circuit Failure

CAN ANY BODY TELL ME WHAT DOES THIS MEAN
I GET THIS CODE 556
DOES THAT MEAN THE FUEL PUMP IN THE TANK OR THE
EXTERNAL PUMP MOUNTED ON THE FRAM RAILL
OR THE FUEL PUMP RELAYS

I would check the Inertia Fuel Shutoff Switch.
Will the truck run?
What year?
What engine?
Duel fuel tanks?

Not if it runs.
Do you have some sort of Super Chip on it?

No There Is No Super Chip In It
It Still Runs
Could It Be In The Fuel Pump Relays
