I had a similar problem with my’99. I took the starter to a shop and had it checked. They said it was good. Put it back on the truck, same problem, nothing, no crank. Kept checking everything I could think of but no luck finding a cause.
My friend said John it’s the starter. So finally I got a new starter and Bam! It’s fixed. Cranks fine now. The starter is shorted or has an open somewhere, just haven’t found time to check for fault in old starter which by the way was only two year’s old.

Don't condemn the starter till you test it. Roll underneath and jumper across the solenoid to see if it will start. Be darn sure it's in park with the brake set so it doesn't start and run over you.

so I have a 2002 f250 7.3 and this morning I went to start it and it clicked for the fuel pump but after that I had nothing I put a jumper pack on it and both batteries said fully charged so I don't know what it would be my dad argued and said it wasn't the starter but I think it is im just not sure.

I might attempt researching your original post with your original description of symptoms and scroll back a page and wind up reading the symptoms of some previous poster not identical to your own.
Ofcourse, its your choice to post any method you prefer but I think you might get more involvement if you post your issue fresh.

Are you sure your new 880 cca batteries are fully charged?
You might want to start a new thread with your problem.

|Peter weichman||I'm having a similar problem, which fuse was the blown one.|

|DieselExhausted||Awesome, congrats! Glad you finally found it!!!!|

Hey, sorry about not getting back to you with a wiring diagram. Seems I'm suffering from CRS lately.
Glad you got it fixed. That's why I always use a meter to check fuses. I've won few flat forehead awards as well, like expecting the engine to start without the engine harness plugged in.

FINALLY FIXED. Does The Diesel Stop have some kind of bonehead award because I should get it if they do. After basically checking the entire starting system from one end to the other I looked one more time and found that my issue was a bloody fuse. Not the smaller kind you can easily test, attached is a photo of the busted fuse, which I looked at several times before today, when I finally pulled it out and popped off the cover to confirm it was in fact blown. Also attached is a diagram I found online of the fuse panel for a 2006 6.0 which matches the late 2003 7.3 liters after they changed some of the wiring, hopefully this helps someone else with late 7.3 fuse questions.
After a long week of searching, I'm not even mad that I missed this fix or how simple it was, I'm just glad it wasn't something worse, glad it is fixed, and glad that I now know everything else on the starting system is good and know a lot more about my truck in general. Thanks everyone for your help.

Alright fellas - I'm at a loss. I pulled the central junction box (CJB) and found no breaks or shorts in the wires behind it. Next I traced the starter motor ignition wire back through the firewall and into the CJB, I tested that wire for continuity and confirmed that the wiring from the back of the CJB all the way to the starter motor is good.
I previously tested the ignition switch following the procedure that RT provided (I only tested the four positions for the start circuit) and found no issues.
I thought my issue may be the DTRS/Safety neutral, I swapped the DTRS for a brand-new one but still no luck.
I previously checked all fuses and relays - they all seem to be good.
I have no idea what else I can check, it seems I'm not getting power to/through the CJB to the actual ignition wire for the starter - anyone have any ideas what else I can check or have a diagram of the actual circuitry of the CJB?
Thanks in advance and thanks for all the input from everyone so far, I've been able to narrow this down but still haven't pinpointed the issue.

Thanks RT, that makes sense, glad to know it's not just something that's not lining up in my truck versus a somewhat unreliable manual.
If you can shoot me a photo of your fuse panel that would be awesome, I'll just make sure mine lines up and fill in any empty spots accordingly. Next step once all the fuses are there is to trace the wires behind it as JB suggested to see if I have a break that's preventing the ignition from actually getting the ignition voltage to the starter motor.

I have found the manual is less than reliable on identifying all fuses. Any slot that has two prongs in it should be considered used by something, so I wouldn't go pulling fuses that were there out all willy-nilly. Ford didn't put extra fuses in unused slots out of the goodness of their heart.
I have an 03 as well, so if it would be helpful, I can take pictures of any area that you need.

|Para_Bellum||Bump on the wiring/fuse diagram - anyone have one that looks like my fuse panel? My issue is that the 2003 manual available on Ford's website has a lot of spots marked "not used" that I have fuses in...?|

That last photo of yours doesn't look stock. I'm guessing someone put a remote start/alarm in at one time. That relay may be to prevent cranking if the engine is running.
Looks like you have a fun time ahead of you cleaning up.
If I can remember, I'll see if I can get you a wiring diagram tonight.
