B16 problems part 2

I have a b16a5 in a 1990 si, and when i start it it stalls and then wont start again unless i give it a bit of gas and then if i dont hold it at about 2000rpm for about 30secs it will die again...only does this when its cold...i used my stock si fuel system all the way up to the line that goes to the fuel rail...should i be using a teg line or any other teg fuel system parts???...anyone else have a similar problem??

what im getting at is what fuel set up did any of you use on your b16a swaps???

I used my stock dx fuel system. I only replaced the filter when doing the swap. Everything else is from the dx.:)

i figured out about 80% of the problem...i pulled the codes off my ecu and it said to check my dist. so i tested it all and my ignitor was done...the ignitor in my old d16 (brand new dist assy though!!) is the same as the b16a one...so swap swap swap, and its all good now, cept it idles kinda funny when cold...either really low or higher than it should or like its got a vacuum leak...i looked everywhere for one, but i cant find it, anyone got any tricks to findin them??
