Try jumping the starter relay on the fender, big stud to big stud if the starter spins really fast then change the relay. If the starter does nothing remove the starter and have it tested. Disconnect batteries before starter removal..

There should be a large wire from the battery to the relay, and another large wire from the relay to the starter. The function of the relay is to connect these two inside the relay long enough for the engine to start. The smaller wires make the relay work. PLC7.3 is talking about the two large wires. If you try it, use a heavy wire. You could even use one side of a set of jumper cables. Don't crank the starter too long, they don't like it and are expensive. Take it out and have it tested. If you don't already have a manual, you should get one. They are very helpful. Take your time with whatever you try, and ask questions when you need info. Good luck with it.

Tommy take your batteries down to the local parts supply and have them load tested.
It is important that you disconnect the battery cross over cables before you test them. One bad battery can be masked by one good battery when they are in the truck with the cables connected. Most people at the auto supply houses do not know this, they are trained on cars that only have one battery.
Several people on here were having starting problems and had the batteries tested. I told them about disconneting the cross over cable and it turned out that both batteries were bad when tested individually.
The solenoid on the fender well only energizes the solenoid on the starter.
These starters are very sensitive to extended cranking periods. It is important to not crank the engine for more than about 20 seconds without letting it cool down for a minute or two. If they get to hot while cranking they slow down and will not turn fast enough to start the engine. This is why good batteries are so important.
As far as jumping the truck, look at the battery cable size. Were your jumper cables that big?
Standard auto jumper cables are a joke on a diesel engine.
