Unhappy LT1 swap wont start. PLEASE HELP!

here is a previous post for reference:
http://www.thirdgen.org/techbb2/sho...65&goto=newpost

now its all put together. it has spark but wont run.
the fuel pump has 43psi
the motor will run if you spray carb cleaner in the throttlebody but wont run without it. the noid light is bright when car turns over, but dim on carb cleaner, and goes out when running gas from fuel pump.
any ideas?
this car is driving me nuts, and any help will be appriciated

oh, yeah, its a 95 LT1 in a 92 'maro

The link doesnt work. Are the injectors getting power?

Yep, link doesn't work. Did you disable VATS from the PCM?

i hope these work.

the noid light indicates the injectors work great when turning over, but key in on position the light goes real dim

i have used a vats disable, yes.

could it be the optispark crapping out?

if it was, the carb cleaner wouldn't make a difference
