what do you mean you ran earth through the injector wires?

hooked a wire from my earth on my batterie to the the injector wire and tested it at where it came out at the compture and the wire was fine so it should be gettin pulse

did you check the original earth wire as well? as that could be the issue, but if all the above are working then maybe you have an igniter fault, perhaps if the ECU detects the igniter is not functioning it kills the injection as well? The other possibility is the injector is clogged/jammed and the ECU detect excessive current draw and kills the driver to protect it, try manually powering the injector and see if you can hear it click on and off.

yeah checked the earths there fine whats a igniter fault? how do i check that i wouldnt think they would be bloked well not 3 of them any way

My mate had 8 blocked injectors on his VH41 after having it sit around for 8 months, it is entirely possible.

Ignitor is what powers the sparkplugs, are all 6 sparking?

yeah all six are sparking so dont think its that well i have to pull the fuel rail out cause ones leaking so ill have a look to see if there bloked

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      Blue slip

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Blue slip

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
