Built KADE fuel problem?

[240sxvaj]

Alright so i have about 21,xxx miles on my built kade, it runs good, drives good, picks up good, and all the good stuff you can think of but sometimes i would have to give it some gas to start up. This happens sometimes only but not all the time (maybe 3 times a month). I check my fuel rail and i smell no gas around that area or anywhere else What can be wrong? :bash:

Built KADE:
Nismo Type B FPR w/ fitting (30,xxx-35,xxx miles)
Walbro 255 fuel pump (30,xxx-35,xxx miles)
740cc's Tomei/Nismo injectors (21,xxx miles)
Z32 fuel filter (30,xxx-35,xxx miles)

Btw, car is N/A at the moment and been running like this for about 1 year or more and it runs good with the Enthalpy tune. This so far will be the only problem i have ran through since the build. Its in a s13 too, not if that matters. :hsdance:

Need more info on my car just let me know :D

Anyone knows?

Btw, my fuel guage reads at 36psi so i know im not throwing too much fuel.

So i guess noone knows my problem? Oh yea, i have done research on it before too.

Is it only for a cold start?

Is it only for a cold start?

It happens after I'm done driving and letting it sit for couple of hours sometimes less. It barely happens to have a start up problem.
