Starter?

What is your question?

Key in the ignition all the lights and dashboard come on, go to crank and it just pops. No turn over. Got under the truck and can feel it hit or "click" with my hand on the starter. Question is how do I know if it's the whole starter needs replacing or just the cellunoid? Or something else completely? Money strapped for a tow, before I can fix it or a mechanic to come to me.

How long has your 1998 Dodge Ram 2500 had this problem?

Few weeks
