Not running properly

Hi all

I have currently fitted a 3071, 750cc inj, z32 maf and a nistune ecu (all off the same car from bob and mapped for correct stuff) 

I have checked inj pulsing fine, what appears quite a weak spark but a spark is present however i think the afm may be wired incorrect or a problem with the afm. 

When i first started the car it ran rough for about 30 seconds (sounded like a top fuel car) then cut out, now i cant get to run atall, turns over fine battery has more than enough juice. 

Just wanted to see if people think my analysis may be right in thinking problem is afm? I am hoping to look more tonight after work and have now found a very helpful diagram which i will double check this evening. 

Thanks for any advice 
Glenn

Spoke to bob today seems could be one of few things think the 750cc injectors not helping to much nor the fact the car doesnt have a lamba. few things to try tonight and see what happens 
Fingers crossed people

good luck!

yep keep calm and carry on glenn
