I have never seen a silver button next to the hood release on my 94 850. I am curious what this is now too.

So I got up the ***** to push that silver button today. I'm not sure what the purpose of this is but its an ignition switch that doesnt actually start the car. It just turns over and over like its going to start but never does. Can anyone tell me the deal?

Sounds like someone installed a button to turn over the car like for timing setting etc.

There is a connector for it near the starter follow the wiring I bet it goes there.
Might also be for spinning over the motor to get oil pressure before starting??

I am also think the PO did it. I had found the connector on my wifes car a couple years ago, thought it was a disconnected knock sensor. So I took off the manifold to do the PCV thing since that was the only way to get to the sensors anyway. Turned out it was NOT a knock sensor connector! Well after looking it over and talking with someone at the dealer I was pretty sure it was a "remote start" switch. Jumped it and it turned the car over with no ignition. Either the PO had issues with the ignition switch and wired that there to "start" the car or he wanted to turn it over without firing for some reason

I would leave it alone and never touch it.

Honestly, the best bet is to disconnect it and tuck the wires out of sight so that they can't be seen or used.

That is, unless you know how to use that button.

Probably PO has a remote start gadget.

On my GLT, I found a custom button mounted near the sport/winter switch. I tried it before I start the car, no idea. Then the other day I change oil and start the car to warm it, occasionally I hit the button. It horns. Well, then I found the steering won't horn.

I've always wanted to install a switch to turn off my fuel pump so people can not take my car.

Noooo Noooo...:P

I can try to catch up the story with that starter switch:

There cars hava common quirk where the starter fails to turn with the key. It could be becuase of faulty starter relay or ignition switch or the very popular PNP switch. So, what PO(s) in these cases would have done is route a wire straight from the starter motor and connect it to +12 straight from battery thru the switch.

So, they use the ignition switch to turn on the ignition part and then use this button to crank it start when the original starting positon with the key doesnt crank the car.

its just that little DETECTIVE kind of story.....but might make sense to few

That does make sense, but I never would have thought of it. I guess in this case, it was a good idea to have.

You know I'll bet thats the case bestharry. The other day when I turned the key it didnt crank but like the third time it did. I'm sure the button is to crank the motor when it wont work from the ignition.

That sounds like a confirmation of the mystery solution. This way, You car now have a handsome 'Antitheft' feature where the thief will not be able to crank it up unless he figures out this shiny silver button...LOL

For some reason I thought the switch was remote and under the hood near the release there. A button that can be pushed while under the hood to crank it while watching something under there. Photos do help.

So I may have another angle on the 'silver button under the dash' issue. I found a manual that said when checking compression to use a remote starter to crank the engine. Does this make sense? Bc that's what the switch does. It cranks the engine. Opinions?
