The other day I was leaving work and when I started the truck, I had a lot of smoke out of the back and no power when in drive. I turned it off and restarted. No problem, drove home. Next day started it and the same thing, it will idle high until in drive and then no power when I push the pedel. Then water in fuel light. Today changed the filter, got it started again. Same problem but now no oil pressure.
99 Dodge Ram Diesel. Bought new, drove to and from work, about 98000 miles.
Any ideas, HELP.
