My guess is CPS since you never mentioned ever replacing it. Every 7.3 owner should have a spare one in there glove box, since its so common a failure. Does exactly what you mention and is why RT mentioned it. Take a good look at the CPS plug as well. Its known to be an issue as well. The three little squares were the pins go into, if they are not closed, meaning the pins must push them open. Then the plug is toast. If it has black or green or white goo in there too, its toast. A plug and pig tail are cheap, use the whole pig tail to get past the brittle wire at the front of the motor. It gets you all the way up to the fuel bowl. Hopefully your in the US, because the only real good CPS is Fords. Up here in Canada they want 360 bucks for one. Less than half that in the US. Order 2. One for the glove box.
