I am brand new to this site and have a steep learning curve ahead. I have watched hours of youtube videos and read for hours on this and other forums. I have a 72 C10 that I swapped a 2005 Sierra 4.8l into, with a turbo setup. My problem is I cannot get it to start. It will crank, sputter for 3-4 seconds and die. AFR does seem high, but I thought I did everything right. We thought the ecu was VATS deleted before, but it wasn't so the plugs are pretty soaked (maybe the problem?). Can someone help me by looking at my build and tune to see if I am missing anything? I thought I did a datalog, but I cant find it. AFR was rich, around 9 or 10, that's all I can remember.
