03 2500hd runs for abut a second - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 03 6.0 will turn over and run just fine for all of 1, maybe 2 seconds, then stall. I parked it for about 2 weeks when my brake like broke, the battery went dead, charged it and tossed it on the tender. Went to start it the other day and this happened. I will try to attach a video of what it is doing. I thought it was in security mode, but that reset didn't work. I tried the negative terminal for 10 minutes, no beans. My thought is fuel pump. My crank position sensor has been making it throw a check engine code, I'm wondering if it finally quit and that is why it won't stay running.
