I got mine when I was 16 or so. I was working for a toy store and I was moving some boxes of merchandise in the warehouse and I caught my wrist on a 16D nail that was sticking out of a pallet. I still remember the meat that was left on it. OUCH!

Dude I hope you get to feeling better and I'm hoping you get Black Ice to running.

I wished I had a nice warm garage to work on mine in... heck I would settle for a car port even.

Walker this is a long shot... but I ran across this. You DID install some gauges. Check this out and see if this isn't your problem when ya get a chance... Like I said "its a long shot" Diesel Place : Chevrolet and GMC Diesel Truck Forums - View Single Post - lack of power

I put in a boost and pyro but I haven't wired them in yet I was waiting till it cranks to make sure they didn't interfere thanks for the consern. I believe we found the problem last week the supply line to the cp3 we replaced and didn't bleed we bleed it last week and got fuel to the "block" 2004LB7 talks about now I just need to bleed the rails and she should fire up I'll be trying it after work today hopefully my next post will be with a first start video

Does it feel like its got good compression? It didn't sound like it from the tail pipe video. You did say you set the valves. Did you follow the book? Just trying to help.
