if you take off injectors and pulse them with juice with pressure on them, you will know if they are working.
check on youtube for cleaning fuel injectors. there a lots of videos on how to clean injectors. when cleaning, you will know if they are working when pulsed with electricity.
have you hooked a code reader up yet?

no reader yet . my mechanic just came by and checked it out , he has a pulse reader the hooks to the injector plug , they pluse like once or twice when cranking and stop , the pink wire is a constant 12 volt , the other pluses a ground , to my understanding , so i may have a ground issue , anyone know what grounds i would have on a n ly6 out of a seira van from 2006 ? curent did my harness and they dont mention a ground at all

a car that briefly starts then shuts off is a symptom of VATS not being turned off. any chance you could have your tuner re-read the computer? could you find someone local and maybe swap computers?

Are you sure you have a 12 volt key on source that stays hot in both the crank and run position?
Sounds like you are in Florida? I'm in Melbourne. If you are close and want a second set of eyes on it let me know.

ktown yes holley drive system brackets
bczee , tune or lack there of , the guy who sold me the engine package said it was tuned for my engine , and vats turned off , wrong on both points , it had a tune for a 4.8 in it . Im am no tuner , this is my first venture into the ls world , been building hot rod sbc and bbc , for 35 years , but even I can figure out the a 4.8 tune wont work on a 6.0 , and one has vvt , the other does not , not to mention I believe most 4.8s had a 24 reluctor , diferant than the 6.0s
all in all the thing that pisses me off is it was back to the guy and he swore it was good , 3 weeks of down time for my lift on a computer issue , thing runs great now though , and the engine apears to be in great condition .
kudos again to Jerad at current , he got me up an running
DID I MENTION IT PULLS LIKE A TRAIN , HOPE MY TRANY HOLDS UP
