Car won't stay at idle

[hungryjoseph]

Car specs : s13, s14 sr20, 255 walboro, fmic, 3" catback.

the car wont idle/stay on. It happened while I was letting it warm up, about to go home from work. I turned it on, let it idle, it dropped down to 800 rpms after reaching operating temp. I waited until I was off the phone before I started driving. The car started idling at 500, to 700, to 500, then got lower and lower, and died. I walked to the gas station and put a couple gallons of 93 in it, assuming i ran out of gas because my gas gauge is broken, so I have no way of telling. I tried to fire her up and she did the same thing as before, which is idle at 100 - 200 for a couple seconds and die. I pulled the relay on the fuel pump and it did the same thing. My intercooler piping all seems fine. I looked over it all, but I know the car wouldn't do this if it were just a small hole or something. I tried starting it at WOT, made no difference. Recomendations?

edit: yes the pump primes

1) Unplug your MAF. If it starts check for leaks between your Intake and throttle body.2) Check for vacuum lines. make sure they are all still attached and none of them are cracked.

i checked for leaks and it all seemed to be fine. the vacuum lines are intact. bad FPR? busted lines? bleh
