I do not have a multimeter, I've read the DIY threads, Im aware of what the issue might be, but...KYP have looked at it and they said it needs to be replaced, it's possible that it's just come loose and floating in the fuel tank, or that it's stuck and needs a clean... Free Inspection from C-RED will determine that.

Got called into work early today :(

Huh, just never heard of their name in conjunction with tuning here in Perf.

When's Corey getting a dyno? :P

I have 2 quotes for Mainline and Dynotech units sitting in front of me :closedeyes::closedeyes::closedeyes:

Morning all

Woo...so you gonna be able to tune me car then? :P

Yeah SAU WA dyno day

Eventually, just got to work something out with the Boss and where to put it first. Is only going to be a 2WD one at this stage

Woot! My car is RWD anyway :) keep us updated!

The last tune was done with what seems to be a fuel pump on its way out. Think that may given me some issues....that tune actually gave me less power than the first tune....which is odd since I've done some exhaust work after the first tune.

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
