Hi guys, I'm having an issue and thought I'd ask to see if anyone here has an idea of what it is. I just got a 2002 Tahoe LT with the 5.3L engine and 65,000 miles on it. 2 weeks ago or so I was having a hard time starting the truck, battery was a year old (it was dad's truck before it was mine), and AutoZone replace free of charge. That seemed to work for a bit, but now I'm having the same issue. If I throw the charger on it for a little while I can get it to start, but would like to figure out what is wrong first so I can fix it. Any help would be appreciated.
