Starting


#1

Have a 04 Avalanche I keep up to date on all services. It hesitates to turn on, I checked battery and alternator and reads like it’s supposed to. Sometimes when I turn the key it blacks out and zeros my radio


#2

Also it starts when I let it run its computer check but, still hesitates


#3

Is there any corrosion around the battery terminals? Are they good and tight? Blacking out and zeroing the radio screams bad battery connection.
