So, I am a 16-year-old kid, who grew up loving diesel trucks and thought it would be a great idea to get one. I bought a 2007 Silverado classic LBZ Duramax, I was driving around for about 20 minutes drove fine went into a store came back out started the truck, and drove about 20 feet, truck stalled, would crank over but wouldn't catch, popped the hood when I thought my batteries died but my terminals were lose I played with them and primed the fuel pump on the passenger side near the battery truck started loaded it about half way up on the trailer and it died again I did the same thing again but didn't get further before it died. Again as I said this is my first diesel and just wondering if one of you guys could help me out if you have had the same issue, thanks
