Hi all

Some of you may know that i already asked something about the "wont crank" questions on another thread, but that other thread´s topic is a little bit different.

Ok here we go:

I own a JDM FD3S 1992 and i flooded the engine, so i put the egi relais and spark plugs out and let it crank.
After a while, it stopped cranking and from this point on, it would not start again.

I checked:
- clutch switch sensor, changed the spring
- starter and solenoid, it works fine ( put it off and brought it to a garage shop )
- there are 11,5v down at the starter
- security relais - i cant find it BUT i heared that the JDM FD3S doesnt have one, or is it only there if you have a security alert on your FD?
- i checked and cleaned the ignition switch on the opposite of the keyhole for starting the engine.

Could it be some mass-problem? I dont think so because it cranked before 10 sec without any troubles.
Ok, i had the click click problem too, but i ordered the pettit booster kit now ( on the way ).

I have no clue what i should check. I even had some thoughts about parting out that FD

regards
Andi

Hi all

Yesterday, my car electrician and i inspected the car and he found out what was wrong with the FD --> i had a big mass problem. This means that the only mass point from the engine to the body were the one on the firewall with the plastic clip on.
Because this cable ran hot after a while, the plastic clip melted a little bit and the car didnt start.

So someone did a **** job on the car, but i will get a new mass cable for the engine/body, so this problem should be eliminated now.

By the way, i searched and searched for the security relais --- JDM FD owners, there is a big chance that you do not have this relais in your FD, like my FD :-)

Thx
Andi

Your follow up will be very helpful for future members who are suffering for the same problem. By mass cable, I think you mean ground cable?

Lawman_AUT

Sry yes, we call it "masse" in german, it is of course the ground cable.

Because one of my ground cables is connected to the ABS unit, i connected the new, fat ground cable from there to the engine and it works fine now.
Of course i fixed the broken connector from the smaller ground cable.

Car starts fine now. In the past, i had the miss miss start problem, which the booster kit from pettit will fix. But since i connected the new ground cable, i hadnt had a problem with the engine start again ( started about 10 times since build in ). But because i already has the booster kit, i will put it in.

So, im back again.
My car wont crank again.

Ok, battery has been loaded and is full.

I looked at section G on the repair manual - troubleshooting.
I measured at the starter at terminal B, there is voltage.
Then i measured at terminal S, but nothing.

So on the repair manual it says, check the ignition switch --> i have done it. This means i put it out, opened it and checked everything for bad connection. Then i reassembled it and put it in.
2nd part would be to check the inhibitor switch, which should be shown on the repair manual at section K. I mean i have the english AND the german repair manual ( booklet ), but im missing section K on every manual.
Where exactly is this inhibitor switch placed?
Remember, i have a JDM FD so i dont have the security relais - its also not needed to press the clutch to start the engine ( otherwise, i replaced the spring on the clutch switch sensor ).

Thx you for your help
Andreas

you realize that the S terminal is only energized when the key is in the start position right? I would like to see the ground go from the lower left side of the engine by the spark plugs to a clean body mount, not the abs, as the main engine ground. the car is a manual right?

Lawman_AUT

Hello mad7tist,

thank you for your reply.
To say the truth, i have to check again if the key was at start position when i measured with my multimeter the s-terminal.
About the ground, i also put a starting cable from the - battery pol to the engine, but that didnt helped. I mean my new grounding cable is huge, my car electrician made it for me and after i installed it, the car ran fine.
But i will put another ground cable from the chassis to the engine just to get sure that grounding isnt the problem.
And yes, my car is a right side drive ( japanese ) with manual transmission.

Thx, Andi

Does anybody have some hints about the inhibitor switch?

Lawman_AUT

So, i really!! read me throug so much threads here.

Reason, my car wont crank.
This means when i turn the key from off to on, i only can hear a clack clack from the airpump. If i turn the key over to start, nothing happens.

So i checked the starter for voltage as i described here. Terminal S on the starter wont get voltage when i turn the key from on to start.
So i followed the black/red wire, which will be connected to terminal S ( and is now connected with my pettit starter booster relais ).
If i am right, this wire leads up to the engine bay to the left grey connector.


The wire will go into another wireing harness, i guess on the front engine bay over to the right headlight, but i am not sure.

So does anybody know where this wire leads to?

I have done a lot of research - so my JDM FD doesnt need to press the clutch to start, also the clutch switch sensor on the clutch pedal has been repaired.

I also shot a picture from my clutch pedal, i didnt found the clutch interlock switch there.



Ah yes, i also put the ignition switch out twice and cleaned the copper parts, so there is no corrosion.
I also put a starting cable to the minus on the new battery and connected it with the engine, but still no cranking...

I guess one solution will be to rebuild the car with a starting button like some of you guys already done.
Of course i prefer to repair the original parts, i dont want to put in a starting button at this time.

Thx you
Andi

BTW: on the 2nd picture you can see a lonesome connector on the middle/left side, does anyone know where it belongs to?

Lawman_AUT

The car is running again!!!!

Dont laugh, but it was indeed only a broken fuse.
But i had to look very sharp to see, that there could be something wrong with that fuse. I tested it with my multimeter, and voila, its definitely broken.

For all guys who have the same probs in the future, it was the first 40A fuse ( left 1 ) on the "fuse holder" beside of the + pol at the battery.
