I touch turns on by itself

take battery out for few minutes and retry

Check the battery and the battery cables.

Try starting it with the battery and the power plugged in.
This seems like a power problem but there's too little data to be sure.

Its seems that your battery is burnt, so go to the store and replace it.

The best way to check for a power drain or a "draw" on the battery is to dis-connect the negative, or "Neg" (-) side battery cable and then connect a test light not a meter, between the "Neg" (-) side battery post and the battery terminal at the end of the battery cable.

With the key removed, all of the doors closed, and no accessories turned on, and also if there is a light under the hood dis-connect it for now. Normally the test light when connected should start off bright and then quickly dim down until the test light is almost not even showing a connection and the filament inside of bulb that is inside of the test light will barely glow and not even light up, this is normal and the only thing that should be drawing power is the KAM (Keep Alive Memory) for any control moudules or accessories that require a KAM. If this is the case then the condition of the battery would be suspected of being at fault and an internal short inside of the battery will not show up as a draw on the battery, and the battery voltage will slowly drop off all by itself with nothing even connected to the battery.

If the test light does not dim down and stays bright, or it will dim down but will also still dully light up the test light, then there is a draw on the battery and if you start removing the fuses until the test light dims down and barely makes the test light filament glow, then you will know what circuit is at fault, but if the light never dims down with all of the fuses removed, the doors are all closed, and no accessories are turned on, then dis-connect the wiring to the alternator and if the test light dims down to almost nothing, then the draw is in the alternator itself.

Common places to find a draw are the vanity lights inside of the sun visors are not turning off or are shorted, the power door lock(s) are faulty, or after-market accessories that are not properly installed, and there is even the possibility that something metal has dropped down into a cigarette lighter or a power point and is making a connection there, such as a watch battery. Also check the wiring for any wires that have been melted together or if they are missing insulation allowing the wires to touch each other or a body ground.

Heres your answer, I also have a envoy and it did the same thing. Have you catalitic converter checked, your exhaust is all plugged up.

I did a warm reset and it worked. Just hold the up key and reset!! good luck

My HTC HD2 has suddenly starting giving text in half english and half french - how to I solve this, it just started on its own one fine morning.

Did you get the battery checked? OR maybe it's an issue with the PowerJack connector on the motherboard...have it checked ASAP.... Also take out the battery and plug straight from the wall jack using the Adapter to ckeck if power is coming.
