Gtr Runnin Out Of Fuel On 9psi With Nismo Pump? Wtf

[R33GOD]

Hey guys gettin my r33 gtr tuned and have run into a problem.

my car is running out of fuel at 9psi @ 226rwk with a nismo intank pump behind her.

The pump was brand new when bought it. Just wanting to know whats goin on and why this is occuring.

Is the pump crap, fuel pressure reg? need some opinions. ecu is a wolf v400

prolly a dumb question, but injectors? (tho would think GTR ones would easily handle 9psi)

9psi what? The rail pressure on 9psi of boost is not... 9psi.

Boost is pressure only, not fuel flow rate.

Anyhow - It'll most likely be fuel pump wiring.

If the pump wiring was not fixed (factory is crap) when the pump was installed, it wont be seeing enough voltage.

[R33GOD]

sorry. 9psi of boost it was having this issue.

As for volts apparently they are fine. He is going to do a fuel pressure test tomorrow to see if its a dud pump.
