my 2005 GMC ENVOY does not start as I insert key in ignition and turn the ignition and it does not start everything is on so it's not the battery is there an ignition fuse that has to be replaced help
There is a fuse but not likely the problem. Make sure all your connections are clean and tight. If you can check the voltage at the battery to see if it is charged, it should show 12.5, 12.6 DC volts if it is charged. Try jumping it to see if it starts.
