hey guys i was wondering if anyone knows anything about neutral safety switchs. Jst bought a 93 Si prelude and everything works great but the car wont start sometimes, however sometimes it stars in neutral. Iv narrowed it down to what im pretty sure is a faulty or broken saftey switch, as the engine doesnt turn at all thus the battery is not dead. Does anyone know how to adjust the switch or where i can get them replaced.

thanks
ps. im new so i have no idea whether i posted this in the right place

Is your car an automatic or a manual?

You posted in the right place.

Welcome to the PreludeDriver.com!

its an automatic.
thanks

Your prediction that this is due to a faulty Neutral Safety Switch could be correct.

The shop manual says that the Neutral Safety Switch only allows starting in Neutral or Park. Perhaps part of your switch is worn out. You probably should just replace it.

I found the following picture in the shop manual on page 14-31. The shift position switch may have nodes on it for the neutral safety switch.

You should probably review some of the material in the manual. The manual is available in our manuals section.

thanks mate i'll check it out later today and tell you guys how it went.

cant find the location of the switch. would anyone know where it is? Im fairly sure this cars manual transmission was changed for auto transmission, if that helps

On the manual transmission version, the switch is located at the clutch pedal. See if you can find remnants of it there.

had the same problem with my brother's prelude. last week its all fine then yesterday those symptoms happen. its an AT btw and after checking it the diagram is also correct. Would isolate the problem soon, and I have been searching online for a replacement neutral safety switch since my brother is using it all the time.

If I remember correctly, the switch is located right along the underside of the shifter mechanism.

Pull the console out and look on the drivers side, just down and under the shifter. You will see a white plastic piece attached, lengthwise, to the shift mechanism. That's the shift lever position switch i.e. neutral safety switch.

I found it at Auto Zone. Link to the part I found there:

Also found it at Majestic Honda: - look at the middle of the image, right under number 36, look down. That's the shifter position switch - it's part number 4 in the list. Two bolts attach it to the housing, and then the split plug connectors attach to the main wiring harness.

This is what it looks like :

And this is where you should find it:
