Assuming you mean the engine dies, you need to clean the throttle body first of all. There is a build up of grime in the throttle body and on the throttle plate preventing the plate from closing completely at idle.

your alternator is bad. Use a volt meter and check the battery when the car is running it should have 14 volts or more. if it dont replace the alternator.
Please rate me.

2004 Trailblazer will not start. Battery and fuses check out to be good.Tach and speedometer jump around when starter is engaged.


It sounds like your battery is ether LOW or the wiring is loose. Check battery cables to be tight and free of corrosion, also check for loose wires to the battery and alternator. if everything is OK, jump start vehicle. If problem persists, take vehicle ot an AutoParts store to have Starting and Charging Systems checked. (no charge).

Good Luck!! Don't forget to rate this post!!

I was gone for a week when I got back my 2004 trailblazer's battery was completly dead. I was able to get a jump and recharge it. it ran fine for a day then the 2nd day out I tried to jump someone else and...

Could be a blown fuse. While jump starting the other vehicle, you could have had a surge of voltage. A bad fuse could be the result of this. Hope this helps. Good luck
