Code 51=Stranded 87

[Saavedro88]

I posted a thread in the General Section but it's gotten only two responses...

My car will NOT run. My supra was turned off for probably about two weeks. Didn't plan on it being this long, but that's just how it ended up. Just finished bolting the shifter and everything back up, went to turn the key... Cranked up a little bit a shook like an old 440. Naturally I let go of the key... Tried to turn it again, I can hear a little wind-up but no crank, wind-up slowly runs down and a huge, a$$ smelling, dark cloud comes out of the exhaust.

I checked my codes and she lit a 51 which reads as follows:

51 Switch Signal


Diagnosis

* No "IDL" signal, "NSW" signal or "A/C" signal to ECU, during diagnosis check.

Trouble Area

* A/C switch circuit
* A/C switch
* A/C amplifier
* Throttle position sensor circuit
* Throttle position sensor
* ECU

I searched "code 51" and came up with JetJock's writup. Got to the point of removing the TPS, but I stripped the screw. (Not too worried about it... I can just hack it off...) THEN I find out that the code 51 has NOTHING to do with my car not starting. So now I'm about 5 steps behind where I started cause the problem doesn't show itself in my codes.


If ANYONE can give ANY advice, I would be most grateful.

A little more info would be helpful. It won't crank but blows stuff out the tailpipe? Doesn't make sense.

The 51 will still need to be fixed after you get the car to run. It's important for other reasons.

 

[Saavedro88]

It's important for other reasons.

No doubt.

It just sorta whirs and I can smell gas vapors coming from the tailpipe. I had originially thought that the starter was slipping or something because it sounds like something spinning like a gear spinning against a belt or something. It will wind down till it dies. My clock will reset itself to 12:00 when it's all the way down...

That's pretty much all the info i've got...

Does it spin faster than normal? Sound kinda like there's no compression?

 

[BorHor]

Gas smell is probably because of all that unburnt gas from trying to start.

You said you "Just got done bolting every thing up and the shifter...."

Please explain to us what you were doing.

I think he said in the other thread he posted in the Gen. Sec. that he rewired the stereo also???I'll bet he didn't disconnect the battery when he was working on it and may have shorted out something in the process. Funny how he said that he wasn't getting any response from the other section and most of the same guys are responding to this thread.

Not really... But I didn't really notice. I'll check again tomorrow.

That's what I had figured...

Transmission was running a bit low on oil, so I swapped it out with some Redline MT90. Also discovered a burned out bushing so I got a new one and a new seat from Marlin Crawler.

What kind of a moron do you take me for? The wires I was working on weren't even in the car while I was working on them. And so far I've had 3 more people post on this thread in less than a day than I've had post on the other thread in 2.

 

[CRE]

Are you hearing the starter spinning freely and the engine isn't cranking over at all?

Three counting mine. Didn't say you were a moron. Somebody asked a simple question, what else were you working on. I took the time to look up your previous thread and gave that info, which you didn't post in this thread. You have to give people as much info as you can so they can help. I simply said that it was possible that you could have shorted out something. That's why the TSRM says to disconnect the battery whenever you are doing anything electrical. You didn't say it was out of the car.

My experience is that pretty much everyone who comes to this forum is a moron until they prove otherwise. A fair majority never succeed.

Maybe I missed it but what spins faster than normal? The starter or the engine? It sounds as if you're describing a starter that isn't engaging the flywheel. If so the only fuel that's going to get injected is from the cold start system and only then if the coolant temperature is below 100 F.

edit: CRE beat me. He must love playing 20 questions as much as I do...

Well said JJ. I was trying to be nice, and just trying to help.

That's kinda what it sounds like... Is that a possibility?


AJ: Sorry man, didn't mean to jump down your throat or anything. No hard feelings?

Yeah that's exactly what it sounds like, and I would assume that the coolant was below 100F... Coolant is like water in the aspect that it's relatively the same temperature as the ambient air right? Highest it's been around here for a while is about 80. I was trying to check the Cygnus TSRM for the starter/flywheel but I have the worst time trying to work that thing, and my dad took my Haynes camping with him by accident. Won't get it back till Sunday afternoon.

Assuming it is the starter not engaging the flywheel, what would this mean? Could the starter just be slipping? Or is the flywheel seized or some teeth missing? I'm gonna try to borrow a pneumatic jack from a friend tomorrow, all I've got are Rhino Ramps and they're useless unless you can start the car...

 

[Saavedro88]

And I'll be the first to admit I'm a moron when it comes to most things having to do with the engine, but I'm pretty solid on electronics and especially stereos and things of that nature.


I'm really sorry if I've offended anyone or made them mad at me. Definitely NOT my intentions. I'm just really fed up with my car right now, and really tired... haven't slept a good night since school started...

Sounds like a bad starter, discharged battery, or bad connections. That your clock dims is telling. Since they're the easiest check the battery's state of charge and connections first. Also measure what voltage you have across the battery (starter would be better) while trying to crank.

recently happend to me, i was attemting to wire a light to my water temp forgot i pulled out the ign fuse.....i still feel retarded :3d_frown:

Lol. I've done stuff like that before to bro. But it's not the fuse, the first thing I did was check all of them.

I ruled out the battery for a couple reasons: 1) It's only about 2 months old. 2) I measured it's voltage: 12.4. 3) When the key is only as far as the "On" position the battery gauge jumps up above twelve; it only comes down when I actually turn the key to ignition. Maybe these are all bad reasons to rule out the battery, but I think my best bet would be to check out that starter first. Are Toyota starters easy to rebuild? I've rebuilt a couple of GM ones, and they were fairly easy...

No offense but it seems like there has been a lot of threads posted lately that you have to pull info from the writers, like JJ said about 20 questions. It's what we mean about posting everything you have done, noticed, tried already, etc.,etc. You, I, and most others don't know it all, nor do we profess to know it all, just what we have went thru with our own problems. I have to pay homage to people like JJ,CRE, IJ, Dr. J,:bowdown: and several others that really know their shit, and take time to help out less knowledgable people like me. Well enough said...
I'm sure you know the battery can show 12v without very much drain on it with very little charge. I had the same thing happen to me with a old battery. I thought it was shot after it had only set for a few days, took and got it checked, it was good just needed charged. Find out the belt needed tightened it wasn't charging. I'd check out the battery first and go from there. And of course your connections.

Battery is two months old yet the car sat for two weeks before this all started. I dunno, for a guy who is supposed to be pretty solid on electronics you seem the opposite. Those are all bad reasons to rule out the battery. Not only is open circuit voltage the least accurate method of determining state of charge but at 12.4 your battery figures out to be only about 70%. It may not be the battery or connections but the point is you don't follow directions very well. Odd behavior from someone seeking help. Not to mention you could have simply charged it or tried a jump before posting any of this. Ah well, if you'd like doing things the hard way be my guest.

Wait... What? I'm not trying to be difficult at all! I THOUGHT those things would rule out a dead battery? I'm sorry if I was wrong... I've already said I'm not trying to be difficult... I thought 12.4 was good considering it sat for as long as it did... I didn't charge it or jump it. That was the reading I got from it before I even started with all the code 51 stuff... I'm not trying to do anything the hard way just the opposite! I apologize again for being difficult...
