Ka-t shuts off when given gas

When I start my s13 it idles fine but when given gas it immediately shuts off...

DETAILS-
Emance tuned ecu for 370cc injectors/ z32 maf/ ka(stock internals)
I have that exact setup... I think its the fuel pump even though I hear it when I turn the key.

If this means anything, when I first installed the z32 maf, 370cc injectors, and the emance ecu the car revved once or twice when I first initially started it. I noticed that it got progressively worse. Im assuming that the fuel pump partially broke? only holding enough pressure to turn the car on? idk im stumped... BTW its a walbro fuel pump any help would be appreciated, thanks
 
it immediately dies like the gas pedal is an off switch or does it stumble a second and die off?
does this in neutral? or only in gear?
 
Check for voltage when car is running on battery
check voltage to fuelpump and u need an fpr w a gauge ...its like important
did u clean out the gas tank?

^His fuel pump screen is nasty as fuck.

I say new fuel pump, full tank of 93 with injector cleaner, and raise fuel pressure.

If hes making fuel press 34 at idle with a, if you say dirty screen could be over working the pump just at idle even worse when you need more psi in your rail once you give it gas. Like some of you said pump probably takin a shit too.
 
fml I typed this whole thing out fuckin spellchecked it... owell basically UPDATE: took the emance ecu out and put my stock one in, now it runs but when I slow down to a turn and let go of the gas, it shuts off.. js and everyone else here is probably right about the fuel pump being bad... it was sittting in shit fuel for like 7months..fml.. the filter is all rusty colored.. im waiting for the new fuel pump to come in maybe monday or tuesday, ill give you an update then. as for the fuel pressure.. kat 370cc injectors... setting it to 43-44 idle (53-54 full throttle) that sound about right? lmk much kudos to sr and js thanks for all the troubleshooting chyeahhhh!!
