Guys,

i just installed a set of Deatschwerks 555cc injectors into my RB25DET.

the car starts but doesnt hold the idle and shuts down after a few seconds. Ive checked, theres no fuel leak or anything thats disconnected.

I followed paulr33's guide on how to change injector values in the PowerFC but im not even sure im correct.

The new injectors are 555cc with latency of 0.75 was what i was told from the guy who sold me these.

this is what i put:

Correction: 67%

New latency: +0.22

Please help!!

have you checked all connections? plugs? leads?

checked fuel lines? checked plenum/throttle body?

any sensor names highlighted in black? (black background)

what are the values for (at ON but not started)

AF-1

THRO

BOST

WTRT

02-1

EXTM

SETTING, AIRFLOW - whats set here?

this is when the car is ON but not started.

AF-1 - IGN and ECC are black

THRO

BOST

WTRT

02-1 - NTR is black

EXTM

SETTING, AIRFLOW - number 3 ( i have a Z32 AFM)

put a wideband o2 sensor up the exhaust and check mixtures, maybe its lean or too rich?

also are the fue lines on the correct way on the rail entry/exit connections?

the car doesnt start up to meaure the mixtures

the fuel lines. i have it set up as from Fuel filter to the pipe that goes to the back of the fuel rail and the other hose from fuel pressure regulator to the other regulator looking thing above the fuel filter

I know this sounds stupid, but when I did some work in that area I left the AAC valve unplugged and yeah, it wouldn't idle.

Plugged it in and off it went.

It was on there, just not pushed down enough for contact

    • Hi all,   anyone know where I can pick one of these up for a reasonable price? I just resprayed my rear trunk due to fuel stain and my new muse spat install.    added a photo for some content 馃ぃ馃憤   thanks 
    • Consider a 35 too...
    • He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 馃槂
    • Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.
    • Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.
