7.3L won't crank
This is for my 2002, F-350 XLT, 7.3L, CC, SRW, 4X4.
I had just cleaned my shop up enough to get the front of my truck in to change both front wheel bearing assemblies (320,000km). Then I got in my truck stuck the key in, waited for the wait to start light to go out, tried to start ... nothing, zip, nota, no crank. I drove her home the night before with out any issues. I'm sure it's not the batteries (tested with a load tester, both are good (and 1 month old each)). When I put the key and turn to wait to start every thing seems fine I can hear the pre heat solenoids cycle fine, all the normal beep, blips and buzzes it's just when I turn the key to start there is nothing.
I looked through a Haynes Repair Manual electrical system and started checking the following:
Fuse 31, Good
Fuse 51, Can't find it
Fuse 61, Can't find it
Starter Relay (307), Good
I have also tried turning the key and shaking the steering column and shifter. I have also retightened the torx bolts on the Park/Neutral switch at the steering column.
Any help or other ideas would be greatly appreciated.

I took a quick look in the dark with a flash light, I didn't see a solenoid on the fender, what side should I be looking.

( last year did the same thing and this sensor was the issue) is there any resolution to this problem.......need your help thanks.............I did read a note from one of the supporters ( Lou Braun) from 2003.........will look into his suggestions as well. 5-31-12

Mine turned out to be my starter solenoid, after all.
I didn't think it could have been the starter solenoid as I had started it dove it no problem. Then went to start it the next day and nota! The starer was not very old so I started looking every where else first.
Turned out the last time that starter solenoid activated it gave it's all and blew the plastic cap to bits. When I crawled under my truck and stuck my hand up to just feel the solenoid as my 7 year old son was going to try and start it for me, things just didn't "feel"right up in there. So I told my son to stand by and I fished my head up with my light and squinted one eye and finely saw what had happened. The terminal lugs were just hanging in the air and all I could hear in my head was that old Service Station attendant from the corner when I was a kid say'n "WHY THERE"S YR PROBLEM SON".
