rb25det running rough and dying

[lazyeyes13]

Hello, I have an rb25 swapped s13 thats running very rough and dying... Its a s1 thats mainly stock with a few mods:
Greddy intake
q45 throttle body
walbro 255 fuel pump
fmic
stock t28 turbo
stock injectors
and I just changed the plugs... NGK bk7's gapped at .028
I will start it up and it will idle rough and when I give it gas I get no throttle response whatsoever.. it completely just cuts out then dies. I have noticed a fuel leak back by the tank. When the key is in the on position, the fuel pump stays on and never shuts off. Also when I changed the plugs, one of them was soaked in fuel down where the plug sits. Can anyone help me please??

sounds like your wiring is incorrect. black with a purple or pink stripe wire is the signal from ecu to the fuel pump. It should come on then pulse signal sends the fuel to the rail. Feels like 3 small bumps when you put your hand on the fuel line. If it's constantly on it's either the pump or the wiring and also sounds like you have a leaky injector in the fuel rail. Update as after you have checked these things.

also has it ever started or is this your first time to crank and attempt startup? is this a premade harness or did you modify the wiring?

I will update after I check those things...
and yes it has been started and driven before, the throttle would cut out some during driving though. Now i have no throttle response at all.
And yes its a wiring specialties premade harness.
