If it cranks, and you have fuel, it should at the very least put out some white smoke.

I am looking at buying a 550 with the 7.3 and it actually had the same issue. Turned out to be the filters in the sending unit within the fuel tank. They get gummed up = no fuel. It sucks but you have to drop the tank to clean them. Check your air filter and fuel filter on top of the engine too. The sending unit is a last resort but might be the issue.

Thanks "Crewcab", the sock in the tank was changed last year, may have 5.000 miles sense. Don't drive it much in summer, I have a Jeep I like ti drive when warm, moving this weekend and need the truck.

One easy way to check the fuel system is to open the yellow fuel drain, with a hose on the pipe directed to a clean container, and key the pump on. You should get a healthy flow. A sputtering trickle would indicate a problem somewhere in the fuel system, be it pump or clogged strainers in the tank, whatever. If in doubt about the flow take a video so we can have a gander.
