Ignition switch or lock cylinder

93 Honda Prelude S 2.2 SOHC Manual Transmission

Not sure which is my problem, the switch or the lock cylinder. Just encountered the problem today when I was leaving work. My car would start but only ran for a second. When I put the key to the on position no dash lights would come on and fuel pump wasn't making any noise. Couldn't operate the power windows either. Finally got the car to stay running. Made it home without stalling. Let me know if you need any more information.

Re: Ignition switch or lock cylinder

I'm gonna take a shot in the dark here;

Accord, Civic and Prelude have a weakness with the ignition switch
which may get worn out over time. Inside your ignition switch, there are 3
little "bumps" that will line up as you turn your key, allowing the car to start up.

Over the years, these "bumps" will be worn out and go "flat" which will make your
switch go back 1 step. You may not notice it on your key, but that's what happens
inside the switch module.

Here's a picture for you, hopefully you'll understand what I mean when you see it.
The switch itself is very easy to take off for inspection. You'll see it right away
if that's the problem.



I just noticed that the freakin' JPEG compression kinda raped the characters on the text
there, so if you have issues reading what it says, I wrote it here one more time:

Position #1
- Will give the car electricity

Position #2
- Gives the ECU electricity, this is
where you hear your fuel pump

Position #3
- This is where your engine crank and returns
to position #2. Remember that if Position #2
is worn out, it will snap straight back to Position #1
and cause the engine to stop. This may happen
immediatley, or take short time before it releases.

Like I said; This is a long-shot, and may not even be close to your issue.
But it's worth a shot.

The "bumps" may be so worn/flat, that it doesn't even move the switch itself
in there, thus, no power/electricity when you turn your key around.

Best of luck, and welcome to PreludeZone.com !
- The few, the proud, the Prelude !

Saying that what you said makes a lot of sense.

Re: Ignition switch or lock cylinder

Thank you for the info! Is the ignition switch easy to get to? Do I have to worry about the air bag?

Not at all.

The first thing you want to do, is to get a Phillips screw-driver and remove
the screws that's holding the plastic around your steering-column.
Once this is done, get comfy up/side/down like you can see I did when I
mounted some speakers and tweeters in my car:



Reach up behind the ignition switch. This is held by a couple of Phillips screws
too, so they are easy to remove. Once this is done, you can pull out the
switch and you'll have it in one piece hanging from it's wire, looking like this:



There are mainly 2 parts of this switch:

The KEY-LOCK
The ELECTRICAL switch itself

Seperate these two, once again with your Phillips screw-driver.
You'll see that it looks like this inside the ELECTRICAL part of the switch:



Insert a flat-headed screw-driver inside that flat plastic part there and
flip it around as you would with your key. This is the same thing that happens
when you turn around your key. The CYLINDER/LOCK part is just there to
recognize your key, allowing that plastic-part to turn around.

#1 Position (ACC)
#2 Position (ON)
#3 Position (CRANK)

So go ahead and start your car that way and see how it acts.
If the plastic-part turns around one step after cranking up, you have found
your problem.

Open the plastic-part and you'll immediately see those "bumps" inside there
as I explained to you in the first post I wrote. If those are worn out, this
will be the only part you'll need to replace. Go get one from the Junk-Yard
or order a new one online. As long as it's from the same model/year, the
connector will fit right in and you can connect everything back up in reverse
order.

- Best of luck! ;)

Sorry to thread jack - this is what's happening to my car right now. I initially thought it was dying while driving due to the good old ignition switch recall, but after replacing it my car continued to die while driving - getting worse to the point where I stopped taking it on the road.

While trouble-shooting I noticed I could keep the car started if I held the key in position 2. I figured I would just replace the entire key cylinder but it turns out the part is discontinued (06350-S30-A00ZA). I'll probably try to find an after market part.

Does anyone know if I'll have to worry about the immobilizer if the new key cylinder comes with keys?
