urgent help on start up issue!!!!!!!!

[projectslider]

hey
i need input on whats happening to my s13 blk top sr when im trying to start it up. i recently installed a brand new ebay sr wiring harness. sent the head to clean (new valve seal, cleaning, rectified from a recent broken rocker arm incident i had) bought a mines boost up 62 ecu, cas, ignitor.
the thing is the car has everything for it to start up. i assembled everything today and i have spark,gas, playing with the cam angle sensor and it started up fine and idled for about 20 seconds and then died , then i started messing with the cam angle sensor again and all it did was start up for a few second and the sputter alot to shut down completly. it did this several times and i cant seem to get it to start and stay at idle.
what can the problem be:

ecu?(its tuned for stock maf, injectors,1.1bar tune, do i need to run stock boost selenoid?)
cam angle sensor?(should i keep messing with it?)
ignitor?
gas(faulty fuel filter?injectors? or fpr?(running stock right now)
coolant temp sensor(i read that if running a 62 ecu on a blk top it need to be replaced)

please help me out here since my goal with the car is to run a gymkahna event on the 24 of august!!jeje

thanks!
