no suprise no start 6.0

[txsrt-8]

Ok so im honestly to the point at giving this truck away. Its a 2007 f-350 drw 117k with 4" straight exhaust, bullydog gt, sinister egr delete, sinister black onix or what ever they call them head gaskets, arp head studs, valve seals, new injectors, new high pressure oil pump, o-rings, ipr valve/sensor, icp sensor, new oil cooler, new high pressure rails, ficm bla bla list goes on and on. Basicly every thing on the top half of the damn motor is new. I was a mechanic for chevrolet but never delt with these other than small stuff. I am the one that did all the work to it and it will not start on its own. You can start it with starting fluid and it will run perfect all the power its ever had but the second you turn it if its done. I know im sure this is on here some were but I honestly don't have the time or want to look. Not trying to be blunt about it just sick of it. I had a 1999 cummins with a little over 500 hp and 300k miles that I would drive around the world before I would take this down the street. Any help or ideas would be great and thanks in advance.
