How long has the car been standing wile you where doing this settup?

maybe chek if theres enough fuel in the tank? fill it and try again

My s13 stood untouched for one and a half year with 50% fuelin the tank, first start where like your cars doing now, but after filling the tank with new fuel and driving it around for 2 days it came though fine..

also chek the fuelfilter if there is maybe dirt..

Here's a suggestion:

A.) Make sure your cams were installed @ TDC

B.) If you advanced or retarded the timing, put it back.

C.) Pull hair out.

Did you do any tuning to make your car run with those injectors and MAF? It sounds like that is your problem to me.
