Coils?
 

So i tried to start my 7 for the first time. The engine hasnt been ran in 2 years. Not seized. I put WD40 in it once a month and turned it over. I went to start it it today and nothing. I didnt have spark. I traced it back to the coils. I have 3 wires coming into the them. I figured i could split the yellow and green wire (negative) to both coils. I have no juice though!

PLEASE HELP!

It is the Canadian spec model.

I hate playing 20 questions.

But, do you have voltage at the battery.
Do the headlights work?
Do the headlights dim when you try to start it.
Does it turn over.
How do you know you don't have spark

And no, you can't just split that wire and run it to both coils!!!! :(

Yes i have full power to my battery. The car wass turing over with ease. I put the battery on the charger for 3 hours before starting it.

I am missing one of the coil wires. It is supposed to go to the 'igniter' so says the wiring diagrams. It is the LY which i assume light yellow.


HELP!

BTW.

I love 20 questions! :) haha.

Incorrect. Read the FSM more clearly. LY is blue with a yellow stripe.

They arent in the manual. If it is not in there that i assume that the wire is just gone.

Even if those wires are not in the diagrams, the keys to the coloring codes are. And i bet they are, the wiring diagrams are just a big PITA

page 50 (B-1) chapter dunno the last one.

ignition system wiring diagrams.......

They arent there. I have looked ever! I am getting frusterated!

Maybe I'm not understanding what you are looking for. The ignition coils are stated on the page i quoted. and ignitors. so be a little more helpful in what you are actually trying to figure out cuz the descriptions i read are fairly vague about a green and yellow wire...... are you looking for something in the engine bay or the wiring diagram?

edit maybe i should look at the 80 spec FSM.

Ya. It might help to look at the right year! :lol:

OK. There is supposed to be 4 coil wires coming out of the loom... 2 black and whites, one yellow and green, and one purple / LY.

My car has the 2 blacks and the yellow/green but NO PURPLE/LY!
I took as much of the loom off that i could get to right in the area and it is not in there anywhere! The wire is no where to be found. :(

BUMP!

I am stilll missing my coil wire. My other SA is the same year and model and it has 3 blacks and one yellow/green.

PLEASE HELP!

Hrm.
Questions:
You are missing a wire to both coils or just to one of them?
Can you take pictures of the terminals were the wire should have landed?
Why are you certain that your coil and not your ignitor, distributor, or one of the plug wires is to blame?

If you've somehow lost a wire without moving the car, you probably will still have it hooked up to the other end of the ignitor which is on the distributor. Take a look and see. You definitely want to make sure there isn't a stray piece of copper floating around your bay one way or the other.

If one of your ignitors has a bare terminal and one of your coils has a bare terminal...

plus if you said it was turning over great before this then you don't need that other wire haha, just what i think, anyways
what does it do if it doesn't start?
does it click?
does it just hum like it wants to start but no sparK?
i don't have juice in one coil cuz my ignitor went out, but i'm not too worried about getting it any time soon cuz i got 2gdfi but that could be something to think about...hmm other questions,
spark plugs, have you checked those?
wires?

Trace down the leading ignition wiring, make sure the leading is connected entirely. then try to start the engine. If the fuel pump comes on, it will run on leading only. Then chase down the trailing.

The car turns over, has a working fuel pump, working lights, working everything! I just have no spark. The COILS have a 3 wires going to them. I will get pictures of them later tomaro.

After looking through my 80 FSM, I suspect that you're looking at a different year. The 80 ignition is different from the other years. There are only 3 wires coming from the fender mounted igniter, YG, B and BW. You need to look at sec 5, p. 15, fig. 5-56 of the 80 FSM and Section B, full diagram, of the 80 wiring diagram. Both references can be found in the link in my sig. The wire colors are poorly labeled in the full diagram, but between the 2 you should be able to figure it out. Be sure to read the introduction page of the wiring manual. It has a list of wire color abbreviations along with examples of how to read the diagrams.

If you can't get the ignition to work, it may be time to upgrade the dizzy and igniters to the FB style. There are write ups on how to do the conversion. bobrx7 has one to convert the 79 points style ignition, the 80 should be somewhat similar. There should be a link in the FAQs or the archives.

I am so confused and just want my car running!

I see nowhere were I need 3 wires. They all have 4 coming off the Igniter. I am literally MISSING a wire.

I think i am going to attempt to do FB style. Do you know where i could get supplys for the conversion?

Junkyard or post a wtb in the 1st gen for sale section. You will need a 12A FB dizzy, J-109 igniters and both igniter wiring harnesses.

Not sure what you mean by 'they all have 4 wires'. If you're looking at an 81+ FSM, you're looking at the wrong one. It must be the 80 FSM as that year is a transition year between the 79 points style ignition and what was installed on all FBs, 81-85.

Firstly start being more precise. You are going back and forth saying they all ave 4 they all have 3, sperated everything when explaining. IE: In the FSM is shows 4 wires and on my car I only have 3.

Second: Did you dl the CORRECT year of the FSM as Trochoid stated. I cant seem to dl the 80 version at school so i cant look at it to help you out. If you find the correct FSM then the wiring diagram should be fine.

You are leaving unanswered questions, and you said you would post pictures but never did.


Third or 4th of w/e: You are contradicting yourself. You say one of your cars has 3 blacks and a yellow green but your identical car is supposed to have 2 blacks a yellow green and a purple one.

So what is it. It could be as trochoid said, that this is the transition year.
Take your time, look through the FSM.

Also the likelihood of actually missing a wire to the ignitor and not being able to find it in the loom IMO is extremely unlikely. What is more likely is that you are missing something key, or making assumptions (such as LY being light yellow, which its not)

1: The car i am trying to fix has 3 wires. (2 black and 1 yellow/green)
My other 80 has 4 wires. (3 black/ 1 yellow/green)
2 of the blacks are tied together with a factory conector on my other car.

2: Of course i downloaded the correct one! I may be blonde but i am not that stupid! :lol:

3: The diagrams are very unclear on what color wires are for the Cali/Us model. I dont know if the coils are supposed to have a wire jumping from one to the other or what?

4: I HAVE VERY VERY CLEARLY READ THROUGH ALL THE MANUALS. :wallbash:

5:It appears that i am missing a wire. It is very unlikely that i am missing on but you never know. Take a look at the pictures.

someone has fucked with your wiring that's for sure...

Post pics of the igniter, it's connectors and the wires from it to the coils. In the factory diagram, you'll need to follow the wires back in the diagram until you find a color designation.

Ya think!!!!!
