here is what my issue is. the car will just start up for a split second on every 3 key turns. i am getting spark and fuel to the fuelrail at the first nut. i have an obd2 gsr harness and from what im reading i need to use this but is this the only way? i didnt know that i could just use it so i stole plugs from it like oil pressure plug, big dizzy plug, vtec,and knock plugs, and the injector plugs. i would like to run the obd2 injectors but i was also reading it just not that simple. i need to know if i should just put the gsr harness back together? it would take me about an hour or 2 but do i really need to do this. any insight on all of this would be greatly appreciate it.

here is my set up:
00' si b16 which is obd2 my car is a 92' RS (all plugs in b16 are still obd2, motor has 56k)
obd1 b16 intake mani with spoon ventuli plate
obd2 tb with map sensor on the top of it
p28 ecu chipped
obd1 LS injectors so still have wire clip plugs obd2 fuelrail
fpr with guage reading 36lbs
obd2 big dizzy plug with big dizzy plug pinned into obd1 harness
obd1 LS wiring harness
obd0 LS iacv
new bosch plat plugs
oem plug wires
obd1 alternator
fuel filter was fine when i took it out of my grey da.

so thanks for the help but me and my buddy tested everything that had to do with the injectors and decided to swap tham out and that didnt get it to start. so we got a noid light hooked up to it and the injectors were not firing while cranking. so i cut an obd1 ls dizzy and put it on and it fired right up.
