Default c5z starts and immediately turns off

Hey guys. Ive been doing a lot of reading and trying all sorts of things and Im at a loss.
It starts with no problem and as soon as it starts it turns off as if I turned it off with the key. I dont have a security light or check engine light. I have gotten remove key for 10 sec message a few times. Ive been trying to figure this out for weeks. I cleared the codes and the only ones that come back are
SDM u1096h
AO LDCM u1016h, u1096h
AI RDCM u1016h, u1096h
BO RFA u1096h

Ive checked all the fuses
Took apart and cleaned ignition points
New fully charged battery
Checked grounds (clean)
Tried both keys
Vats are turned off (sd tuned)
Hooked up to a tech2. Didnt read crank sensor so I replaced it.

Ive gone over the car and everything seems to be connected.

Here is a breakdown of mods done since last time it ran.
F1c blower
Ecs front mount intercooler
Innovative over drive crank pulley
Flip drive
Blower cam
Rockers
Fast 102/nw 102 (ls2 style with caspers wiring)
Iat sensor (maf removed)
Motor mounts
2" kooks
3" x and catback
Carbon driveshaft
Built trans and rear
Pfadt trans mount
Lg coilovers
Other parts too but you get the point the car was torn down pretty far.

Any help would be greatly appreciated! Sorry for the novel just wanted to give as much info as I could remember.

Tom

Is it just a cold start issue, will it eventully start and run if you keep trying?
I have a similar issue that started after getting a SD tune after H/C install.
I think I found the problem with mine but I could be wrong...
