Would a dead battery stop your key from turning on in a 2003 gmc envoy


Sounds like a flat battery. Just enough to power your lights but not enough to power the starter motor. Try recharging the battery.and check battery connections are good.

2002 gmc envoy stalls when turning and slowing down


I am going to assume the check engine light is not on.
I would check the throttle body to see if it needs to be cleaned, and check the idle air control valve to see if it is working. The computer controls idle speed by the amount of air coming into the throttle body.
The ac problem is probably something different such as low freon or a cooling fan problem.

2002 Envoy died, no power to anything. No click when trying to start it... just nothing. What the heck could it be? I'm thinking alternator. Before it died tonight, if I were to be pushing the


Sounds like your alternator went out or not making good connection at the battery terminals, preventing the battery from being charged. If the battery does not charge, you will use up the battery energy to maintain the vehicle running UNTIL you deplete the battery. the more accesories you have on, the faster it discharges till the point of killing your ignition on your engine. You definitely have a charging issue, more than likely, your alternator went out.

2002 envoy battery died - replaced and now wont start on Driver 2 and wants to stall at all stops on Driver 1 - also stalls when the air conditioner is used


Very common problem with Envoys and Trailblazers. For Driver 1 Clean your throttle body with throttle body cleaner while the battery is disconnected. After this is done, re-connect your battery, drive around for 5-10 miles while the computer resets and relearns. Do the driving with the A/C off and the defroster off. Your problem will be solved. I've never heard of not starting in a different driver mode with just changing the battery.

Replaced battery on 2002 gmc envoy. now it goes dead when air is


your alternator may be the problem here. When the AC is on, the motor has to work harder, and the fans need eletricity to spin (unless they are powered by a belt, unsure). If the alternator can't keep up the battery will die.

2002 Cadillac DeVille wont start (even w/new battery!)


well first off, check the glove box light blub, make sure it shuts off when you close the door, check it by pressing the switch with your finger to make sure it shuts off, also check under the hood for the light there if there is one, pull the bulb, and the same thing for any bulb in the trunk, then check again after a day to see if the battery dies, if it is dying while the vehicle is not running then it is the battery, if it is dying after it is running then it is the alt. you can check that also tho with a multimeter set to the DC volts setting, place the black end <the ground to any grounded area> and the red end <the hot lead to the back of the alt. > it should be reading higher then 12 volts, normally should be a higher reading then 12 volts... if you are getting a lower reading or just 12 volts then the alt. is bad and needs to be replaced...hope this helps you out...

If your 2002 gmc envoy or sierra will not even turn over with a kown good battery try starting it in nuetral then go back to park and try starting again. There is a park nuetral safety switch that can malfunction. Turn the key on then shift into nuetral, then turn fully to start.
