well thats good to hear you worked things out, i just came back from looking at it and found out a few things that i will not post up until it's resolved so as to not lead people in the wrong direction!
We don't all have the experience you have, it may be black and white for you but to others its not that easy, this is why we are here to learn and help each other.
i'm sorry i dont know as much as you but when you're in a frustrating situation you try what you can to fix it, and it dosen't...
no crossed wires, black, blue, red, yellow.
what 180 are yout alking about, the CPS on the cams?
When i turn ignition on the tach does not jump a bit.
Checked continuity between;
Ignitor-Coilpacks =good
ignitor-ecu=good
cps-ecu=good (before and after running new wires)
new ECU in and it is not the answer.
I'll have to guess it's something with the engine harness, dare i pull it out and check every wire one by one? OH GOD!
BTW this is the first time i'll ever say this in all the years, i hate my supra right now.
soi checked continuity between all the wires in the diagram http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=40 and everything checks out so im pretty damn sure its ECU, i dont' know what else it can be.
Will let you know when i get the ECU
damn sounds like youre in the same boat as me, your cps plug might be loose or dirty, i've had this issue in the past and that's all it was but now i'm not so sure. im thinking ECU.
Ill post an update when i get more info.
You're talking about checking continuity? i've tested most wires, ill do the rest next time i work on it.
I might try running my own wires to see if the signal will get there.
Possibly a new ECU
jdub, it's not those wires... i've tried it many times
I have no other electronics added, still code 12 and no spark, CPS wires are resoldered, coilpack plate is grounded, resistance of coils checks out, igniter good, main relay good, tach does nothing when ignition turns on.
what else to look for?
WTF? i've never come across advancing your cam gears in any thread on any supra site... if you read the manual it tells you how to set the timing belt the way it was designed for by TOYOTA. They even give you marks where to set it to.
wow time to dig up an old thread... for those who wanted to know since i am the original poster i wanted to say to whoever may be researching that blocking off the lines will not overheat your system.
You may have other issues if it is overheating like described in hottscennessey's posts.
