03 2500hd runs for abut a second
 

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.

crank sensor.. check it first. crank sensor not working it wont fire and wont send fuel signal to pcm

Ok, I will replace it anyways because it has been throwing a code for a while now. Hope this works!!
