The first diagram is wrong on that page. just follow down further and you will see the correct wiring sequence. USe this image insread , alot clearer courtesy of UAE BooST.

Can it possible a airlock? I mean isn't our fuel system vented somewhere so the fuel can flow smoothly? What if it blocked and not allowing the fuel to flow at its capacity. You know maybe a breather somewhere is blocked or clogged ?? Jst like blocking one end of a pipe and trying to...

HAs anyone checked the Air Flow Meter if you still have that? I know for a fact that the AFM or a busted intercooler line will not let you rev past that rpm. I read through most posts here, but see reference to TPS but nothing about AFM, maybe I am missing it. Check it.If its not...

I like the Zeitroninx. They just came out with a new software which is Palm PDA based and that means no more lugging around the laptop fpr dataloging. And it is very small so fits anywhere. There support is great as well.

Get a whole clip. from either Jarco or Venus. these two are the most reputable, but they won't have any until November, i think.

Thank you 935. I was actually able to figure it out by looking at the diagrams. From what I have read, my injectors are wired in a wrong sequence and I will try to fix that first. Not sure if that what is causing all this problems. I'll keep this updated.

I am posting a new thread so as not to confuse anyone with my injector threads. Also posted n Supra Forums..trying to get help anywhere I can. I am working on my 1jz and was tracing the injector wiring down to the resistor as it was wired by the previous owner. For reference, the car...

The RC's and the Densos are a lot better. If am not mistaken, of SF, a lot of guys say that the Venom ones were not very reliable, and that they were actually rebuilt/upgraded injectors rather than new ones. I am not sure though, check with guys here as well. RC and Densos would be the way...

I have had weird posts in my threads as well lol :biglaugh:

That would be awesome if I could do that. Now how do I connect the connector with the injector wires attached to it? This is reversing something i did not do, so here goes the questions lol Any other info would be awesome. I know at the moment there are 2 injectors per one resistor...

HHmm.maybe I am mistaking the blue for the Lavender? Thanks for the pictures, but in those pictures i can clearly make out the injector color.

Well, if you read earlier, that is exactly what I am trying to do. I did not do any upgrades myself, the previous owner did. I am already aware that 550 is too big, and possibly overkill. I am merely trying to get the questions I have , answered, and so far only Drunk Medic ,935 ,and Jeff has...

Thanks Jeff, I got the car with the injectors on it, but it does not run right at all. I needed to make sure they were the MkIV 550cc, and not something else. Never seen them in person before hence request for a color chart. maybe i'll take some pictures, but one thing for sure, they are of a...

Kool thanks man. I will call and find out how much it is.

Its not for mkiii, its going in the 1jz

Anyone have a picture of the MkIV ( US Spec) 550 injectors? I am trying to compare to ones in mine, but I need to make sure they are 550's and not 440's. I am actually looking for the color photo if possible. I know they are supposed to be purple but how purple is it? :icon_conf Mine...

If you can find a MkIII in the junkyard, you can pull the lug nuts off it.

IS the 1jz intake plenum gaskets the same as a 2jz ones? I opened mine up to get to injectors, and found the lower one foldered and was bolted down. I don't wanna flaten it out and reuse it, it be leak. Where can I get them. Thanks. Moe

LOL, you may wanna do the Maori Haka next time you rare getting ready to kill it, then it will know for sure the war is on.. lol
