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.

anyone?

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.
