When you first turn the key to start, do you see the "wait to start" light? Any smoke from tailpipe? Fuel above 1/4 and batteries good?

Disconnect the wires from the fuel bowl (leave them disconnected for now), replace fuse #30 under the hood, and try starting the engine. (Do it in the order I stated as well.)

Report back on the results.

I suspect the bowl heater is bad...and the above instruction is the cheap and easy way to test for that failure.

Since you mention only having 29 fuses in the engine compartment, make sure you are replacing the fuse for the fuel bowl water sensor & fuel heater.

Do you have a helper?

Have you checked the frame rail fuel pump?
For about 20 seconds after ignition key is turned to start position, the pump should make a humming sound and you should be able to touch it and feel it vibrating.

My quick suspicions are...
1)bad bowl heater causing a blown fuse
2)bad fuel pump

Check and get back with the result.

EDIT You can also run wires from the battery directly to the pump to test it.

Also, if you change the title of this thread many more members will help.
The title needs to indicate your problem. Help us help you.
All the title is doing is announcing that you have a 7.3 truck.
All of our trucks are 7.3 trucks.

You can unplug the ICP sensor right at the connection on the head and the PCM will go to a default value. This is an easy way to eliminate that sensor being bad.
