It Won;t Turn Over
Hello Everyone
This is my first post. I will do an introduction in the appropriate section.
I have a 2002 SD with a 7.3. It is not equipped with a cat and is not OBD II compatible. The truck has 225K miles on it.
When I engage the ignition to the first stop, everything lights up. When I turn the switch to engage the starter nothing happens. I do not hear well but I cannot even hear a click.
My thoughts are the solenoid or the neutral the neutral safety switch. I don't want to miss something simple before I start testing everything.
I appreciate any and all suggestions.

I would start with trying the gear selector in neutral and park, wiggle it, after that start with the batteries and start checking connections, solenoids. I don't remember the superdutys having a particular flaw for start ups.

what he said.... If u have a test light, check to see if you are getting power to the small wire on the starter when someone turns the key for u. If it lights up, it is the starter. U can try tapping it with a hammer to see if it wil start.
If there is no power, we will have to work your way back.

Batteries are hot and alternator checks out fine
Thanks Everyone
The batteries are hot and the alternator is fine. I have tried giggling the shifter in neutral and park with no results. I have tried banging on the starter with no results. It is snowing here so I cannot get under the truck but I do not feel it is the starter. I have been down that road before.

Try bypassing the solenoid...The smaller wire to 12v. mine is on the pass side fender wall..12v on that terminal should turn over the engine with the key off..If no click of the solenoid its bad. try jumping the 2 larger terminals that should engage the starter also.
That is if its the same wiring as my 99. No banging on the starter... Magnets break..

Still No Luck
Hello Everyone
I have tried everything mentioned above. The starter checks out. The key switch is new. I am thinking it is a relay somewhere in between. The small wire going to the starter is not receiving current when I try to engage the starter.
If the is a solenoid on the passenger side fender, I cannot see it.
As luck would have it, it has done nothing but rain and snow since the truck quit starting. It is in my driveway. It never happens at the farm where I have nice warm dry shop to work on it.
Again, I am open to any and all suggestions.
Thank you,
Roger

You have to be more specific pls. That small wire gets hot from the solenoid on the side of the fender behind the battery..Does that solenoid click? That solenoid gets its power from the key switch. If the solenoid behind the battery isn't clicking when you turn the key you need to get a test light and see if the small wire on that solenoid is getting hot with key to start.

Try the relay in the diagram below. Take it out and look for corrosion around the base, then take another identical relay out of the same box that isn't critical (like the accessory delay relay) and put it in there. If that lets it crank, then you know it's that relay and you can get another one.
You can usually get them from Ford for about $20.

Check the nuetral sw on the tranny. The pcm controls the relay After it senses park N..OK
Didn't mean to be misleading.
