Check the battery terminals for corrosion and also that they are tight.

If that checks good, get a meter and check for a voltage drop from the power wire to the starter, and also check the ground cables.
Based on your post it sounds like a bad battery cable, but It's hard to tell because you have no punctuation and everything is written as is if said in one giant breath.

You say when you turn the key the radio and light comes on, but the dash ODO does not. What happens when you go to start the truck? does everything turn off and click or does the radio and everything stay on?

 

yes, there is an E.S.D. on these trucks that you can by-pass by introducing a ground to the relay under the hood. I actually recently ran across this same problem with someone stranded on the side of the road in a durango. after looking for a min I realized her engine was locked up and therefore the starter would energize but wouldn't turn over. See if you can spin your belts by hand.

 

i jumped out some like ignition box thing on the left side of the sterring coulum and not really meaning to got the truck to start but once i take off my jummpers it shuts off. the odomiter and stuff comes on when its started

 

it will turn over but after jumping out this little black box on the left side of the stearing colum i belive its the ignition switch. do u know where this esd is located
