cylinders 1,3,5 arnt fireing its def a fuel problem cause the spark plugs in cylinders 2,5,6 when u pull them out after having the car runing plugs are wet with fuel and smell like fuel changed my ecu with another rb20 one did the same thing suspect its a wiring probem but have checked the wires seems to be fine :D

check the suspect injectors for continuity.

checked the circut in the injectors that arnt workin to the computure circuts fine changed the the computure over with another rb20det comptuture made no difference changed the cas over with another made no differance :)

Check the injector pins on the ECU with a test light see if the problem is in the loom or at the ecu end, as you tried a different ecu almost certainly the loom somewhere, just keep tracing it until you find the issue, pain in the ass but not much else you can do.

This happened to me a few years ago on my pulsar gtir after I installed a fmic. I accidentally disconnected something but cant remember what its called. it might be a resistor pack or something for the injectors..

Anyway its the silver box thing on the passenger side, under the bonnet just near the top of the suspension turret. its got a plug on it with a few wires coming out of it.

It may not be a resistor pack. But my sr20det definitely had this plug thing that controlled the injectors. The silver part was just a shield that covered the plugs and I think there was 2 of them. I accidentally put tension on the wires with one of the stainless pipes I installed for the fmic which was enough to break the contact on the plug.

    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )
    • But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?
    • Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.
    • Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
