I have a 1999 Tahoe LT that runs great. the that just started is that if i let it sit for about 3 or 4 days without starting it then it will not start.
something is draining the battery. The alternator, starter and battery are all new. It usually is after 3 or 4 days. I drove it to a shop and they had it about 4 days but they couldn't find a problem because the car starts everyday when they have it. The mechanics said it needs not to start for them to find the problem. I don't know !
