Fuel cut or what?!?! Help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

1jz_240 · 01-21-2011, 01:00 AM

Alrigt so I have a 91 s13 with a ka24de and I've been changing everything around the motor slowly just to ensure reliability because it has 215xxx miles on it and they can only last so long but I want it to last until I can collect the rest of my 1jz swap parts.

Anyways. To the problem. When I start out like from a stop in first gear almost everytime it like bogs for a moment then it's like it finally gets gas fed to it and it finally picks up power and goes. And it usually does it shifting in to 2nd-5th until I get to a little higher rpm range. Does anyone know what it could possible by? Fuel injector? Fuel pump? I have no idea. And help would be appreciated.

thank you!

what fuel pump? did you swaped the sock of the FP out? also check your fuel psi and fuel filter in the engine bay.

lastly report back

sock filter is in the tank. pull the sending unit out and you will see it attached to the pump
