I have a 2003 ram 1500 5.7L Hemi. I went off roading for a few hours with everything working fine. I then turned off my truck for about ten minutes and when I tried starting it back up, it sounded like the engine started to turn over and start but it immediately died. I was thinking a pulley went out but they all spin freely except the crankshaft pully. Any ideas what i'm dealing with?
