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
