Here is what you need to do to find the problem.
Have a friend push the clutch down, turn the key on, anxd push the starter button wheil you take a 12 volt trouble light and hook the ground clip to the engine black and hold the probe to the large starter terminal, it should light up.If it does not then probe the large starter terminal where the + battery cable is attached and see if it lights up. if not you have a fuse or ground problem. Make sure you have a good ground where the ground strap is attached to the engine and the body. If you have light then while your friend holds down the starter buttom probe the small wire that runs to the solenoid, it should light. If not you need to work backwards to the ignition key, the clutch switch, and the starter button all the while checking for voltage with your test light. take it one step at a time in order and you will find the problem. I do not know if Dodge uses fuseable links like Ford does but if they do they are inline within the postitive cable to the stater solenoid and or the solenoid to starter / key switch wires.
