I own a 91 Honda Civic Hatchback Si with 496k miles (5 speed Manual).
Recently, I have been noticing that my car will not start unless the clutch pedal is pushed down to the floor with extra force. The clutch foot pedal clearly makes contact with the floor but when you turn the key you get silence. When you proceed to step down a little harder and turn the key, the car starts without a problem.

Is there a simple adjustment that can be performed to the clutch pedal mechanism.

I remember replacing a white hard plastic grommet on my brake pedal mechanism that deactivated the brake lights from turning on continuously. Hope its something similar
 
This problem will be similar to your brake-light issue.

Attached to the clutch pedal is a clutch-interlock switch similar to the one attached to the brake pedal. It prevents the starter from operating unless the clutch pedal is on the floor. It has either come out of adjustment, or its grommet is broken.

Get underneath the dashboard with a strong flashlight and take a look. I vote for a grommet problem; these do not normally come out of adjustment.

I would have to agree that your clutch disengage button style sensor is beginning to fail in some fashion, and I'm presuming your slave and cylinder are in good condition and it only needs to be rammed to the floor to start it and not each shift... You can either bypass the switch or source another piece to fix it really easily.

The '88-'91 Civic has a cable-operated clutch. There are no hydraulics involved.

Well it looks like the clutch/brake assembly needs welding.
I can see cracks on the metal horizontal cylinder that is located between the clutch and the brake assembly.

As I depress the clutch pedal, I can hear squeaking and cracks are seen expanding ready to come apart. I do not see the white clip on the clutch assembly. I can see the white clip that I previously installed which deactivates the brake light switch. Not sure what else is up there but it sure is hard to depress the clutch pedal by hand.

Come to think of it, what would cause the pedal to be hard to push down in the first place
 
This assembly belonging to a CRX looks very similar to whats on my 91 Honda Civic Si, and since parts are shared between the two, it must be the same assembly..

Please advise
 
Any idea if the whole bracket assembly is still available?

Wrecking yard. If none in CA, try AZ.

Bent and cracked, now I'm looking for a new or used pedal assembly

So I went ahead and started to remove the pedal assembly. I removed the fuse box for better access.

Removed the pin that holds the brake booster to the pedal and pulled out the brake booster about 2 inches from the firewall.

I still haven't removed the clutch cable from the inside because I'm not sure how it detaches from the clutch pedal. I will have to use a mirror for that.

There is a nut that is holding a clutch sensor. The end of such sensor has a wire which i have yet to disconnect. Also not sure how to remove that but it looks like I have to remove it in order to spin the sensor out of the pedal assembly.

There are other horizontal bolts that I'm not sure if they have to be removed.

I am slowly studying the assembly and feel like I'm close to removing it.

I have NOT dropped the steering and hope that it is not necessary. There is a plastic vent that runs very close to the steering that seems to be in the way but it doesn't look like it attaches to the assembly.

My questions are the following:

Are there horizontal bolts that need to be removed?
Does the clutch switch spin out when removing the wire?

Where is that dreaded upper last bolt that everyone says is a nightmare to remove and FIND?

PLEASE ADVISE
 
ok...got the clutch cable off.

I can see a small thin rubber cover just above the assembly highest point. I pulled back the rubber cover and I can feel a small bolt. I haven't been able to actually see the bolt.

Looking for a mirror to see whats going on up in there.

One thing for sure is that it looks like part of the upper pedal assembly has a second piece that comes off it and attaches to the firewall. It sort of looks like a ramp where the highest point is the part that attaches to the firewall. That metal bracket is different looking, meaning, different overall color and thats what throws me off. It seems like this has to be that hard to get to bolt/nut.

I hope it is the dreaded hard to reach bolt.

Not sure what to do next but I will keep posting my steps
 
ok...after reading a few threads I now understand that the last bolt is NOT located on the firewall but is located above the vent ducts.

Now I have to figure out how to remove the ducts.
 
Got the son of a "b" out...Had to remove the duct, however, I ended up bending and squeezing the other ducts because I could not slide them or take them apart. Not easy...

Now I have to find a pedal assembly for my 91 Honda Civic Hatchback Si, 1.6L.

Hopefully I find one quick before I end up forgetting how everything goes back together.

The pedal assembly is bent and cracked with pieces of metal missing at the horizontal support located between the clutch and brake pedal..

Jeez....

If anyone out there knows where to find one of these please send me the info.
I am trying to stay away from junkyards but it might be my only option.
