Default Start engine w/o clutch

It very much irritates me that I have to press in the clutch to start my 96 SC2. I"m used to popping a car into neutral and then just starting it. If I disconnect the sensor on the clutch will I confuse the upshift light too? (I'd like to get rid of the upshift light too but I believe it will cause me to fail CA SMOG).

I believe the sensor to make you start with the clutch pedal depressed is so you dont try to start the car while it is in gear (and the clutch not depressed).

I believe it is a simple thing to remove but haven't done it myself. Surely someone else can answer this.

Default Re: Start engine w/o clutch

I removed my safety switch on my hyundai elantra 04' Its really easy. If you stick you head in the foot compartment and look under the clutch pedal there will be a little button that lines up with the clutch. That is the switch.....I guess you could just tape it down? Im sure you can remove it but then i dont know if it will start without it.

Some remote car starter companies make a bypass for it. you should check with bulldog or some of the companies that make remote car starters.

I'm sure it would be pretty easy to disconnect the switch then jumper the wires. As far as what side-effects that could have, I have no idea.

Saturn makes you do that for your own good. most other automakers make you press the clutch to start too. You could jumper the wires in the switch under the clutch pedal and start whenever you want. the PCM will "think" the clutch is being pressed down all the time. Your cruise control will no longer function if you do this. Pressing the clutch will disengage cruise control.

The clutch switch does NOT disengage the cruise control. It's at the bottom of the clutch pedal travel. Before it ever closes, the PCM has determined that the revs are skyrocketing upward, but the vehicle speed isn't going up, therefore the clutch is being disengaged, and has thus interrupted the cruise. Obvious test for this: put the clutch down part-way with the cruise engage. You won't open the clutch-starter switch, but the cruise will disengage.

I had a Dodge Omni that had a cruise interrupt switch at the top of the travel, exactly like the brake pedal switch. But the S-cars, at least in '96, have no such switch.

The day I bought my waggin, I unplugged my clutch-starter safety switch, made a jumper out of about six inches of 18-gauge wire with a .250 male blade connector on each end, and jumpered the terminals on the connector. The main reason I did this: imagine your PCM going up the spout. Or your coil packs. Or even something on the fuel side, like the fuel pump. You still have the starter, but the engine obviously won't fire. You're in a bad spot, one that's dangerous in which to get out and push, but 50 feet ahead is a driveway to a parking lot. Well, turn the key, let the clutch up, and for a BRIEF moment, let the starter motor propel the car to a safe spot. I've done this on at least two occasions with previous cars, and would never own a stick-mobile without this capability. Just don't do this for more than a few seconds, as that little electric motor is designed for vehicle propulsion.

Plus, it's nice while working on the car just to reach in thru the window, throw the tranny into neutral and twist the key to start 'er up.

Oh, and I use the cruise almost every time I drive.

I dont have the clutch safety switch in my SL2. Did a auto to manual swap and decided not to install one. The cruise control works just fine. But it will not disengage when depressing the clutch pedal, only when tapping the brake or accelerator.

On my 95 sl1 the clutch switch failed and you couldn't start the car. I drove around for a couple of weeks with the switch connector jumped with a paper clip. Eventually, however, I did replace the switch.

jump the wires. No adverse effect on anything really. I have my wired together for an alarm and it works fine...the only encounter i've had have been people turning the key to turn on the radio and started the car...they soon learn quickly, and you learn to tell others before they decide to do so...

Attention Re: Start engine w/o clutch

Well, if I may add my two cents...

Here is a simple test to see exactly when your clutch switch engages:

Hold your key in the "start" position.

Slowly depress the clutch.

Chances are, your engine will not turn over until the clutch is nearly to the floor.

What does this mean?

It means that in order for this type of switch to effect the cruise control, you would have to depress the clutch to the floor each time you shift--as almost noone does. Instead, the cruise is driven by the computer (PCM, [P]owertrain [C]ontrol [M]odule) sensing the RPM's shoot up excessively without a change in vehicle speed. When this occurs, the cruise will disengage until you depress the "resume" button.

There is no harm in jumpering this type of clutch switch. As I see one person suggested, the simplest thing to do is just to wrap the switch in tape and then if you ever need it for anything you just take the tape off and it returns to its original state. Alternatively, you could simply cut both of the two wires which are attached to the switch and tie them together.

One thing I did not see anyone mention is that some clutch switches (especially in foreign models) are wired CHEAPLY, and use a technology called reverse continuity -- what this means is that the switch does not break or complete a positive charge by being depressed or relased. In simpler terms, this type of system will have only one wire attached to the switch, and uses the vehicles ground (by the switch merely being attached to something grounded such as the clutch pedal) to complete a circuit. This being the case, you can simply remove the single wire from the switch and attach it to something grounded.

No matter how you do it, I have never run into a problem in any case with disabling a "neutral safety switch" as that is essentially what a clutch pedal switch is only on a standard instead of an automatic. The difference being that on an automatic, since there is no clutch, the safety switch is in the gearshift making sure the vehicle is in park or neutral if it is allowed to start. Otherwise, stadard, or automatic; anyone could just go around starting their vehicle in any gear, causing it to lunge. So with that I offer you this piece of advise: If you ARE intent on disabling your car's neutral safety switch, please refrain from starting your car in any gear other than neutral.

As for the case where the gentlemen gave the example of someone being 50 feet from a safe parking lot .. well, I guess maybe I am a big guy, but I would prefer to push the vehicle to safety over using the starter to get it there. Reason being, as he said, the starter is intended to turn a flywheel, with little resistance; not to propel a vehicle with its transmission engaged. But hey, if the starter is under warranty, and you can do the work yourself, and its cold and rainy or snowy and you just want to get home--by all means, stay in the nice warm vehicle, use your starter to get you to safety, and deal with the reprocussions later. I do hope you have a battery with a fair amount of cranking amps though, as if you don't, you may not even make it into the spot you so desperately wish to travel to in that not-so-distant lot.

Regards,

Diesel.

This much you can determine by looking at the switch. It's on the floor. Contrast this with a brake pedal stoplight/cruise switch, which is on a bracket at the top of the pedal's travel.

The jumper method doesn't even require any removal of tape. It's easily removed/reinstalled. I wouldn't recommend the paper clip, except for brief moments, as it's uninsulated.

Try getting out to push on the Lodge Freeway in Detroit, where, if you pull off on the shoulder, you better not have too many coats of paint or you'll get side-swiped. Shoot, there are places here in Madison where opening your driver's door can turn your SLx into a three-door. It's not about size (or comfort, or convenience), it's about safety. I can push my wife's F-150 up and down a gravel driveway with ease. But exiting a vehicle in a traffic lane is an inherently life-threatening exercise. Of the times I've had to do this, it's never affected the life of the starter; I probably couldn't say that about my own keester if I had gotten out to push.

Years back I worked with this fool who thought he had to be the first one out the parking lot at the end of the day. He parked his S10 backwards so he could fire the truck and speed out of the lot. He went so far as to remove the clutch interlock so he could start it in gear.

It worked great until I went out at lunch jacked up his truck and stuffed a concrete block under the differential....

A few years ago (well, many years ago), my Dad was taking us somewhere in our 58 Ford. The engine stalled at a traffic light and wouldn't start. He was able to move the car to the side of the road using the starter in low gear without the engine running. Can't do that with the dumb clutch switch. Although, maybe starter motors were a bit tougher 60 years ago.
