A friend of Mine has (2) F-550 - 6.0s, '04 &'05 I think [they were the first 2 years of production]. The older one had a sensor go bad, oil or fuel pressure, not sure which. It would not fire at all, computer shut it down. It was dificult to diagnose, but after a few attempts at replacing the batteries & some other stuff, the dealer finally found it.
That truck blew the air tube from the intercooler to engine off when brand new, the replacement had better clamps.
