04 f550 6.0

While it is a good thing to know that you have the required 48vt that voltage has to be able to get to the injectors to do anygood. Wieing issues are one of the 6.0's more common problems. Loose plugs/connections, wire chafes, broken wires and corrosion of wires and terminals.

A quick field test is with the engine running wiggle and pull on the wire harness comeing from the ficm if the motor changes up or dies, then check the harness and connections.

FICM is dead It must be 48V ALL of the time.

yes ficm voltage is checked at cranking. general rule of thumb if it goes under 45 it is no good! but theoretically it should stay at 48 the entire time. but dying down the road isn't a super common ficm problem. ficm is usually only issues with cold start.

Solved. Hpop

yes that sounds like a died down the road problem
