car just stopped working!??!

[180ways2slide]

i have an sr20det and im running a microtech standalone with 4x msd coils etc.
now my problem is the car was idling in the driveway and all of a Sudden the car idles lower, then i hear it start to misfire, so i got to tap the gas and it dies completely and when i let off it runs again but really bad.my first thought was the gas was low and i needed gas, but now the car will start for a quicky( a real quicky ) and die. i did a self test on my laptop and the car has spark and the injectors are firing. fpr gauge is going up on cranking so i believe the pump is pumping.

where do i start to look now? has anyone had a similiar problem

is it possible for the fuel pump to come on but not pump, cause after letting the car sit for a couple of hours it starts right up and then dies. and she will start up and die a couple of times, then nothing! now she is just cranking like i ran out of fuel. my walbro is only 2 weeks old can it be defective

If your Fuel pump works then check

TPS
IACV
MAF

Check those and the rest of the sensors

tps is calibrated from microtech. iavc is not used andnot running a maf. but what color is the power wire to the fuel pump from the sender unit
