Guess I'll be known as Doc shorted/frayed wire John, as that sounds like your problem.

Could be a wire is almost broken or frayed enough to not allow enough energy through the weakened connection and energize the system/components.

Broken/frayed harness wires are common with the 7.3s...I found 2 almost frayed through, one broken, and two nearly broken wires in my 2001 7.3...and I have only about 101k miles...so it has been stirred, not shaken!
