Have you checked the wiring? Read about code 51 in the electrical/ecu section? You know, for a guy who joined in 2006 and has amassed nearly 1700 posts you seem lost about a lot of things that have been covered here many times. Oh wait....you're Canadian :)

Figures. More weird Aussie stuff. Probably the same for Canucks. We'll just blame it on Her Majesty :)

No, it doesn't unless you measure for it. I was just focusing on the no spark because once you get past that IGf should take care of itself. You know, for this kind of stuff a logic probe works too. Not as good as a scope but much cheaper. It'll at least tell you if pulses are there.

Target is not 2.3K ohms. That's maximum, the limit allowed. There really isn't a target. All you're looking for across IDL and E2 is less than that. It's usually much less...

Hey, cut the kid some slack. He's tryin' to help. Welcome back btw :)

Yeah, sometimes a scope is the only tool that'll do the job. NE and G are reluctor based btw. Output is sinusoidal and needs to be a minimum of 1 volt p/p at cranking speed to bias the ecu's A/D converter. They're usually much more unless speed is low, magnets are dead, or air gaps excessive...

Ian: Ground path is through the choke. Nashman: You can't be serious. Better not quit your day job, whatever that is. Dave: PM me if you need more help. This is simple stuff...

^ If that were true the mirrors wouldn't be working :) Choke is at connector C19. It's up under the rear hatch panel: http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=25 The reason voltage drops when the load is connected is simply because, well, it's being dropped across...

You're welcome. I don't hand them out easily :) Fwiw the coil and igniter can be checked by flicking the primary (IGt) to ground (do it quickly) while looking for spark at the coil secondary...

Did you check the power side of the ignition circuit? Btw, nice to see someone who understands how things work and knows how to troubleshoot them correctly. My compliments...

^ Listen to this guy, he knows of what he speaks. Also try turning the engine off, unplugging the ISCV, and restarting. If idle is high (1500 or so) odds are the valve itself is working...

Clearing is always wise but just so you know it doesn't apply to 51 because that code doesn't get set in memory. Put another way it's self clearing. Doing it for the other codes is good though. Keep in mind some won't come back right away because certain engine parameters must be met first. 52...

^ 51 is going to be TPS, AC switch on in diag mode, or neutral switch off (if auto) in diag mode. It's not because you removed the compressor. The ECU has no way of determining if one is installed...

Reminds me of all those "how many XXX does it take to change a light bulb" jokes... You have two. Why not look at the other one?

Meaning closed loop. And a vacuum leak isn't going to be the cause of his problem...

Lol...you had me there for a moment :)

While the comment about the O2 sensor is normally good advice it's highly unlikely the CO would be where it is if the engine wasn't in closed loop. Mario: there's no limit on CO2 because it's not a regulated pollutant. It's a "good" gas, an indicator of combustion efficiency. The higher the...

A common problem. So you removed it? Not good. Put one of these (http://tinyurl.com/yed4wx) in the return line...

^ How exactly did you test those items?

Persistence pays off. Sorry I wasn't more help (there are many things that can keep the main relay from closing) but I'm glad you found it. Like Kenny I would have left the harness in the car and troubleshot that circuit with power applied but whatever works for you is all that matters...
