I have a 2007 ram with the 5.9L diesel, manual transmission. It left me stranded in a parking lot, will not crank over. My batteries are good. I had to make do with what I could find on hand since I was away from home. I tried jumpering the clutch pedal position switch, the starter solenoid, and cleaned the battery contacts, no dice. Tapping on the starter didn't help either. I'm guessing it's the starter at this point?
