took mine to the dealer they told me there are 12 different grounds on the truck, one of them had shorted. Mine was on the front of the engine driver side near the valve cover. They just cleaned the contact area and replaced the bolt. when one of the grounds short out it shuts down the whole pcm system. good luck!

I had the same problem with my 97 ram diesel.
