leaky fuel line? If your fuel line is leaking then its gonna tell the ecu to dump in more fuel. White smoke means your turbo is goin bad.

too much fuel is black smoke

If you think there is to much fuel might als be a leaking injector

more details, Why do youthink its too much fuel?, what have you tryed, done?

[Slpr s13]

because wen it starts bogging it smells like fuel and white smoke. turbo is fine spools good. pulled hose from pvc ans smell like fuel. i can literaly see my gas gage go down... wen it starts bogging i wont idle ill shut off. then hard time to crank i think its getting flooded with fuel?

no fuel leaks anywere..

[RYAN_S-14]

take the rail out of the manifold and pressurize the system see if its got a leaky o ring

do you have a FPR? stock fuel pump?what ecu?

all these things can affect your fuel

[Slpr s13]

yes it has a fpr. walboro pump stock ecu. never had problem until like last week. umm so how do i do that test you just discribed

remove the fuel rail from the manifold, turn the key to the acc switch to pressurize the fuel rail, look for leaks.


make sure your FP is at 3 bar and if your running a Nismo FPR make sure you have teflon tape on the screw

[Slpr s13]

how about 02 sensor or injector them self

[fliprayzin240sx]

Wouldnt hurt to change the ECU water temp sensor, specially since you said it start bogging and shit when its up to operating temp.

[Slpr s13]

yeah because it comes and goes wen it want it to be so umm maybe ecu huh.. or wiring harnes.. umm

[mack97]

go for temp sensor first. i had a similar issue and this (temp sensor) fixed it

[Slpr s13]

koo alrite ill try coolant temp sensor. anything else guys?
