Leave the starter alone....On the starter solenoid on the fender short the little wire to a big wire going to the battery. The engine should turn over does it?????

 

Have tried a different key? If you have one of the new keys with the chip in them and they get damaged the vehicle will not start. Other than that, if it will start when the solinoid is jumped then the solinoid should be your problem.

I bet there's no fender solenoid on the 2002's. My 03 doesn't have one at all. I did some testing tonight and here's what I found. The starter motor has an integrated solenoid with two poles. One has a large gauge red wire which is the battery + feed. There's a small gauge yellow and green wire, that's the signal wire coming from relay 307 in the fuse box under the dash. When you short the red wire to the yellow-green wire, you are sending current through the integrated relay's signal circuit, meaning the integrated solenoid is still good since it closes the feed circuit. The only time there is current that goes through the yellow-green wire is when the key is in the start position. The current goes from the key switch to relay 307's signal circuit, which closes the relay feed circuit sending current to the yellow-green signal circuit on the integrated starter solenoid via of course the CPP (which you don'y have) or the DTR (Which you do). The green-yellow signal wire closes the integrated starter solenoid's feed circuit and the truck starts. Don't take the starter out yet, instead try pulling the relay out of position 307 and either put in a new one or take the blower motor relay at position 301 and put it in 307. If the 307 relay was bad, it should start, if not, look at the DTR. I'm betting on the 307 relay being bad. Check your manual for the STARTER RELAY and BLOWER RELAY locations on your truck, the 02's might be different than the 03's. Of course, if you have a fender solenoid, go directly to 99F350sd and do not pass go, as I cannot test for that circuit, he obviously can.

 

You're overlooking the fuses under the hood, as someone already suggested. You have more fuses than only what's inside the cab. Check those before you bother going much further through the troubleshooting process.

 

If we gotta tell ya how to do that you probably can't
