GTFC's "What are these plugs" thread..., Updated to Pics #2 Options

[gtfc115]

people are gonna hate me after all this...

i got my car out of the shop cuz they dont know what's going on. there's a lot of problems with the wiring and i want to get it narrowed down. let me explain the symptoms: first of all, the shop left the main white fuse plug unplugged, so needless to say, they couldnt get power to anything. within an hour of looking around, i figured that out and plugged it in. WHAMMO i got headlights (hi/low) the door chime, locks, lights on the doors, and the guage cluster lights up...thats about it. no sunroof, no power windows, cd player doesnt turn on, no blinkers, no windshield wipers, no fan for the vents. all minor stuff for now, i just want the car to start.

now, when i turn the key to start up, i can hear the circuit opening relay click, but nothing else happens. i had a couple friends over to help out and we ran 12v straight to the starter and the fuel pump relay and got the motor cranking, but there was no spark so it wouldnt start.

so with no power getting to a number of things, i want to go through all the leftover plugs that are layin around to see if they should be plugged into something.

here's the first one. it's probably the EGT sensor. 1 black wire, 1 white wire. it comes out as shown in the 2nd pic.





theres a lot more...i just want to go 1 at a time

thanks a LOT in advance...ive come to find i dont know nearly enough to be doing this swap. shame on me.

By the way, ChrisD from Alltrac.net did my harness. i am confident with his work, and dont mean to say that there are a lot of problems with it...there are just some bugs that need to be worked out. probably the shops fault

You want to see this beast running as bad as i do right...RIGHT!!!!

yeah im pretty sure that one is for you egt sensor. all the plugs are Keyd, meaning that they wont plug in where they dont belong. so if you see a plug try to plug it into anythig u see around. also make sure you have your ground cable hooked up to the tranny and the chasis of the car.

[gtfc115]

k, thanks Lagos. before you guys think im just too lazy to figure this all out on my own, believe me, i'm trying. i have an alltrac manual and my celica manual and all kinds of wiring diagrams, but im not too good at reading the scematics...and even if i was, i dont know where the different engine components are in the engine bay.

these next ones look important...1 is probably a ground, the other, i dont know, but they look like they go together.
both wires are light blue. one has a black stripe, and the other a white stripe.



(black with a white stripe)

[gtfc115]

anyone?

[ChrisD]

Hey Cory,

OK, it sounds like your shop has done some wierd stuff to your car. I'll do my best from here to help. You can always find me at celicatech.com as well. In the worst case event, I would always take the harness back for investigation. Of course that would be a worst case scenario, as that would add a bunch of unwanted time.

It sounds like you are having some very odd problems. FYI, I only mess with engine control features. IE. the things that power your motor. Interior devices would not be affected by my wiring.

Some things to check.

-Did you plug in that single thick wire that I said needed to be connected?

-There is a 3 wire plug, 3 fat wires, they need to be connected. Are they?

-Make sure the ECU is connected

-Check the following parts, to make sure they are plugged in: Ignitor, Coil, Fuel Injector Resistor Pack, Fuel pump relay, Fuel pump resistor pack, Distributor plug, Injectors.

-Check ALL fuses to make sure they are not blown

-Check that your battery is making power

-Check that the plugs beside the ECU are plugged in

-Check your starter relay

What exactly was your mechanic doing? Did he take the dash apart at all? Was he doing any wiring in your interior?

To be honest, it sounds like something is going on behind the scenes with your ignition switch. IE. when you turn the key something is not switching like it should. I need to know more about the car.

[gtfc115]

yeah i lengthened that fat wire and connected it to the other plug.

the all the ecu plugs are connected

all those plugs are in, not sure which one is the 3 fat wire plug you're talking about.

ive checked all the fuses i can find, the first battery they gave me died, but i got a replacement, the started relay is plugged in, and thats the only thing that works when i turn the key... i can hear it clicking, but nothing else happens.

as far as i know, the mechanic didnt do anything inside the car, however, in the time after it left the shop and was towed to my house, it sat there for maybe 2 hours tops before my dad got home to push it in the garage, my s-afc, and RSM were stolen...but they werent wired in anyway.

there is 1 plug that looks suspiscious, i'll go take a pic of that.

[gtfc115]

here it is...it has a plastic cover on it (notice the cut wire on the ecu ???)

[gtfc115]

i just spent like 2 hours ripping my dash apart to find any loose wires or plugs , but that one is the only one...plus a small 4-wire plug right behind the cd player.

i dont understand why nothing on the inside works anymore. no windows, mirrors, brake lights, turn signals, wipers, clock, cd player, vents, sunroof, the light by the sunroof...nothing

[Rjb23]

Check the big green fuse in the driverside kick panel should be am2 or something like that its a 40amp square fuse it controls the radio, gauge cluster, windows, pretty much everything inside the car.

[gtfc115]

checking....

hey Rjb im reading your thread on mr2oc...that sucks man...i've gone through a lot of BS with my swap, but i cant even compare. glad you got it to the point you're at so far.

[ChrisD]

The one with the plastic cover is a connector for grounds. Those wires are all connected. No need to touch that.

I'll have to check my ECU pinouts to see what that wire is. If I didn't connect it, there is likely good reason.

Stupid question...but is your fuse box in the engine hooked up? That is where everything on the inside takes its power from.

Time to check the voltage of the B+ wire in the diagnostics box.

[gtfc115]

this and all the others look pretty corroded

[gtfc115]

+B wire is getting like .5 volts

[Rjb23]

Corrosion should be fine as long as that one is not blown. I'd check all the fuses first thing in the engine bay and in the inside fuse box.

Thanks, just keep working at the swap when you finally get it running you'll be so happy, I know I was. Now if I can only get it to run on all cylinders.

[gtfc115]

yeah i've checked all the fuses, they all look good
thanks.

there's still a lot of plugs in the engine bay that arent hooked up..gonna need to figure those out eventually. i know some will be for the AC which i wont have.

cant wait to get it started at least

[ChrisD]

+B wire is getting like .5 volts
[right][snapback]343944[/snapback][/right]

Definitely a problem.

[gtfc115]

let me go make sure im checking it right...i got a multimeter and put the red on +B and the black on a ground...set it to DC volts and it only goes up to .5 when i have it set to 3v

[gtfc115]

yup, definately only .5v...

[lagos]

for all those little fuses, buy a little fuse test light. sometimes those little fuese can seem ok when they are not. check all 3 fuse box locations in the car....there is one on drivers side, one on the passengers side (unde the glove box) and the main one in the engine bay

look where you ecu is. there should be 3 plugs hooked into the ecu and then 3 plugs that connect right above the ecu (sort of to the left ) make sure all that in hooked in .

make sure your main engine fuse box plug is pluged in correctly ... you sort of have to push down, and this little lever will pop up to help lock it in place. make sure its fully locked and making a solid connection

jack up the car an look under where the back of the block and intake manifold is. there are some plugs for the knock sensor as well as an engine ground wire.

so far it sounds like something simple that you might have missed.

[soulshadow]

If you starter won't start take a look at the starter relay. Make sure one wire is for the 12V+, Neutral start switch, GROUND, and one that goes to the starter.

Im guessing that the 12V+ wire isn't connected to the battery. You will have to redo your relay again.

God, dam why the heck didn't you do it yourself in the first place?
Don't you feel mad that some thieves stole your stuff?

[gtfc115]

hmmmm, didnt know about the fuses on the passenger side...i'll check those first thing tomorrow.

like i said, there's still a lot of extra plugs and i got pics of all of them, but they dont look like they should be keeping the engine from at least cranking.

we hooked up a 12v straight to the starter and got it going, but it wasnt making any spark

[gtfc115]

[right][snapback]343972[/snapback][/right]

yeah everything about my swap so far pisses me off...my first and MAIN mistake was getting a mr2 clip, and then taking it to a "family friend" type of shop first.

[Rjb23]

Did you plug the little black wire into the starter? There should be 2 wires that go to the starte the one that bolts on and then there is a small one that clips in kinda like the one of the pic you posted.

[gtfc115]

OMG OMG OMG OMG OMG i just opened the fuze box and made sure everything was connected good...didnt think i really did anything worthwhile...i put the key in and EVERYTHING WORKS....i didnt try starting it yet, but OMG what a great feeling, im out of breath from running inside to type this...WOW

[gtfc115]

the blinkers work now, the radio, the vents...i heard the fan on the radiator turn on...

now i need to know what kind of things i should do before i try and start it.

there is one major thing i know of...the pic explains it


so thats 1 issue...another, i KNOW i will need a new clutch line because when i got the car towed, i noticed immediately that something was leaking, and when you push the clutch in, fluid squirts out of the line, which i can easily disconnect (not good)

ummmm...O yeah, i dont know if the engine even has oil in it...i cant find my dipstick...i have 2 dipsticks that they gave me in a box with all the extra parts

[gtfc115]

the fuel pump relay is making a really loud buzzing sound

[Rjb23]

Where is your fuel hose that goes from the fuel raill to near the throttle body I don't see it in that pic it should be like 3 or 4 inches long.

[gtfc115]

man this thing's a mess...

sorry, im a 3sgte noob...im ashamed i dont even know where the fuel line is
(sorry for the blurry pics, i thought they came out better)

damn dood. .that motor is CLEAN! i cant believe u were going to sell all that.

its hard to see anything thats not hooked up from those pics.

[gtfc115]

anyone think i should try starting it?

im just worried about that hole where gas leaks out. i have that screw in there, but that doesnt seem like the best solution. i dont know what should be in there though.

also, with no dipstick, there's probably a hole where oil will leak out. i'll have to jack up the car today and try to find where the dipstick goes...

[Rjb23]

No get the fuel leak fixed first, and the missing dipstick isn't going to hurt anything.

[lagos]

you could start a major fire ...buy that cold start injector hose and a new dip stick tube form toyota before you try to start it anything

This post has been edited by lagos: Oct 13, 2005 - 4:16 PM

[gtfc115]

i fixed the leak...tried starting it, and i get no spark. it turns over and over, but nothing.

[Rjb23]

Do you for sure have no spark or are you just saying that because it wont fire up?

[gtfc115]

took a plug out and it wasnt sparking.

also, i dont know if it makes any difference, but i checked, and its not throwing any codes.

[lagos]

bust out the multimeter.... put the key to ON, and start testing the harness plugs that go to your coil and your ignitor, write down all the voltages you get from each of the wires and post them here.

[gtfc115]

k here's what i got:

the larger black plug with 5 wires
1: 12v
2: 0v
3: 12v
4: 0v
5: 12v

smaller plug with 2 wires
1: 12v
2: 0v

[lagos]

sounds about right, just off the top of my head. are you sure the harness plug is connected to the bottom of the distributor (its hard to see, you have to get your hand behind the distributor cap and feel around) and that the cap and rotor are new?

*sigh*

boy im starting to get angry that i spent so much money at that shop for them to leave so many plugs UNPLUGGED. GOD...the plug was there, but when i pushed on it...it snapped into place.

they arent brand new either...but we'll see what happens tomorrow.

[right][snapback]344399[/snapback][/right]

you mean the distributor harness plug wasnt connected and broke? bust out some crazy glue and try to fix the plug

[gtfc115]

no, it wasnt completely connected, so i snapped it into place.

i just tried starting it again but still nothing...pulled a plug and still no spark.

[lagos]

here is something i just realized about your car . you battery is relocated to the trunk, right? how did they run the ground wires back there? there should be one wire that just grounds to the chasis and another one that grounds to the tranny. is all that hooked up right?

[gtfc115]

a ground to the tranny from the battery? No i dont have that.

the battery is in the very back corner on the drivers side. its grounded right under the plastic panel that comes off on the rear suspension...thats it...

can you show me where the ground should be on the tranny?

This post has been edited by gtfc115: Oct 13, 2005 - 8:56 PM

[lagos]

run a ground wire to it... it bet that **** will fire right up

[gtfc115]

can i just put it anywhere on the tranny? then run it to the battery?

i'll have to do it tomorrow, its too dark now.

i should have just sent a wad of cash to you guys. you've been more help than the shop...i told him all i had to do was plug in the fuse box to get everything working (so far) and he was like "yeah i probably just mocked it up temporarily and then forgot about it" pshhhh...is that why i gave you thousands of dollars?! my friend who's been helping me said he went up to the shop and talked to the guy and he said he probably lost money working on it...sorry, but...GOOD.

[celicast3sgte]

make it easier on urself the battery grounds to the chassis like a system would right? ok so just ground the tranny to the chassis too you should just take a 8-4ga wire and run it from where the tranny bolts to the block (with a connector attached) then with a connector on the other end bolt it to the firewall.

[gtfc115]

well...now im worried that's not the problem...
here's where 1 ground is on the tranny, right near the shift cables


and here's where its bolted to


This post has been edited by gtfc115: Oct 13, 2005 - 9:09 PM

[lagos]

there is like a 12mm bolt right on top of the tranny that the ground cable goes to

[gtfc115]

^^^^

[lagos]

hmm ... yeah thats the right spot for it.

do a ground test. find a few places where you were getting 12v at, and touch the black wire from the multimeter to an unpainted part of the motor and tranny to see if it still gets 12v

[right][snapback]344424[/snapback][/right]

seems fine...

[gtfc115]

what about this ground? its just kinda hangin out...

[Rjb23]

That ground should run from the top of the alternator, it should bolt there and then plug into a wire that grounds to the passenger side strut tower.

You will see it, its the only wire pretty much on that side of the car, and it definatly the only plug that that plug will plug into.

[gtfc115]

well...its bolted there, but nothing else is connected to it, and i cant find any plugs that looks like they go with it...here are the 4 spare plugs i have on that side of the engine...probably AC

[Rjb23]

It should be bolted to the top of the alternator where it attaches to the block not near the a/c should be a black plug.

[gtfc115]

[right][snapback]344448[/snapback][/right]

hmmm...i remember there were 2 plugs that didnt match, that the shop had to splice together. could it be these?

[Rjb23]

No they would match up.

[gtfc115]

i think once i get some money together, im gonna get a new distributor and wires. should i get the coil/igniter too? u guys think thats even part of the problem?
