car sat 2 months, turns over won't idle

Hi

my car (s13 sr20det '91) was running great 2 months ago. just been sitting.

car starts and immediately dies. a few times the car has started and idled but is a bit rough, then as rpms rise it dies.

there is pressure in fuel line. no fluid leaks. no vacuum leaks. unplugged afm - no difference. unplugged o2 sensor - no difference. unplugged iacv no difference. o2 sensor heater circuit has continuity. afm has voltage (20-30mv) when car is on.

if anyone has any suggestions as to what I should try, I would appreciate it. i don't know what i'm doing.

car details:
91 sr20det red top drift beater manual trans
z32 afm, aftermarket catalyzer, tuned pfc, fuel pump, injectors, s15 turbo, exhaust mani, intercooler, oem coolant overflow tank
