My boyfriend's Tahoe needs to be jumped every time he uses it. The problem is worse in cold weather or if it hasn't been started in a few hours. The battery is fully charged when it won't start, but still needs a jump to get started. He has taken it to 3 separate Chevy dealerships in Miami, but none of them have been able to find anything wrong.

Please help! We are at the end of our rope! Any ideas are welcome.

Welcome to the forum, are you saying it cranks good, but won't start, or it won't even crank. If it won't even crank, I'd have to check the starter wiring circuits.

If it cranks good, but won't start, have a helper crank it, while you check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure.

At first if started every 6-8 hours the battery would be fine and it would start no problem. If you happened to not drive it for a day the battery would have no charge and the engine would not crank.

I'd get a jump and make sure to drive it frequently and everything would be fine, until I didn't drive it for 12 or more hours. Recently a nasty cold spell hit and the car cant even keep a charge for more than an hour, no interior lights, no cranking etc.

Ive taken it to 3 dealerships and nobody can figure out what is wrong with it. The battery might be out of juice now as it hasn't been changed in a few years but this has been an ongoing problem the last few years that has gotten progressively worse. Ive also experienced other intermittent electrical problems like the radio and A/C not working for periods of time, then working fine for periods.
