Hello. I'm having problems with my 2007 Yukon the radio won't turn on and the battery's voltage drains to the point that i need to jump start it.I've had the battery and alternator checked and they check out fine , we have also checked the fuses and they are fine also after i've jump started the Yukon and weve driven it around it gets to the point where i will have to jump start it again and again if i try to turn it on again. I had the battery replaced three years ago at a G.M.C. dealership. thank you.

If you are planning on keeping your Yukon for several more years, I would recommend the Duralast Gold battery from your local Auto Zone. The Duralast Gold has an 8 year warranty, 700 CCA at a cost of $149 and no charge for installation or disposal of your old battery.
If you don't plan on keeping the vehicle, they do offer less expensive variations of the Duralast brand. The Duralast Professional is $129 and has a 7 year warranty.
Sears has a Diehard battery for $115 plus a number of fee's for disposal of old battery and installation but only has a CCA capacity of 525.
For your vehicle I would recommend the Duralast Gold, I have had mine for over 4 winters and no problems.
Good luck,
Regards,

My guess would be the anti theft security system. When this system starts to fail, it turns off the starter from the ignition. The fact that you can hard start it proves this.

Hi there !

I won't say its an alternator problem because the alternator only charges the battery when its on, And it should start with the jump cables even if the battery and the alternator are bad. your Issue is not clear. Does the car start when you jump it ?

Make sure that the belt isn't extremely tight and they the belt tensioner isn't liked up by pulling in the belt. It should move and spring right back. Make sure engine isn't locked up. And please explain what happen with the vehicle. The fact that you replace plugs and wires and fuel filter for a car that's not turning is throwing me off. So right now we are going all over the place. But definite look at belt and tensioner I've seen a few times that a bad tensioner will make the belt wrap around tighter inhibiting the engine from turning.
