Then either your alternator is not working properly and keeping your battery charged, or you have some parasitic electrical drain.
 
The better autoparts chains can do a battery and alternator 'load test', where they can test that the alternator is putting out full voltage and current. Have this done first. You may have a bad diode in the alternator.
 
Once you know the alternator and battery are in excellent shape, verify that you don't have any corrosion on your battery connections, up inside the cable connections, or where they attach to the starter and engine ground.
 
Then you will need to have an electrical shop check for what is draining the battery. They can put a current monitor on the battery, and see how much current is being drained out, and then start unplugging fuses to help isolate what is in the ON state when it shouldn't be.
 
Just only as an example, not to suggest this is your problem, but I had a relay go bad in my 97 Suburban years ago, where it was constantly providing power to the rear heater unit and blowing low speed air constantly. If the car had sat for any period, the battery would be drained and dead. It could be power seats, windows, A/C, just about anything.
 
Good luck

I am having issues also with my 2007 Tahoe not starting - my issues started a lil over a month ago - I went outside to crank my car up and it wouldnt start - I have had tohave my car towed 5 times in the last month!! Everytime the dealership has an excuse but several days later the same thing happens. Just last week the delearship had my car for 4 days and the only thing they could come up with was my "key is not reading" Seriously how in the heck does it just stop reading both of my keys the same time????? The 1st time they gave me an even lamer excuse - it was my battery but I had already tried to jump it off ....... Today is no different, my car is the dealership again and they STILL dont have a clue as to what is wrong with my truck. I also have a Viper Remote Start Alarm System on my car but that has been disabled for over a month now because of all of the issues. I have put an amazing amount of money into my car and over halfway done paying for it so trading it in is NOT an option! Someone please help me please : (

I bought a 96 Tahoe "Project" a few weeks ago. It was in pieces. I put the engine back together replacing what needed to be. Got the engine back in and fired it up. Ran great sounded real good but had a miss to it through out engine range. While trying to pinpoint the miss I started having starter trouble. Replaced the starter and no start. I have checked everything I can think of and replaced most everything. New plugs, wires, fuel filter, pump and relay. Replaced cam and crank shaft position sensors, TPS, and most other sensors. New coil and mod. Cap and rotor are good. Even rented a diag. computer..."PASS, No codes found." I will be pulling the intake and valve covers today and check injectors and valves. The ONLY thing I've noticed and I think may be a problem is my spark is not blue, the best I can get is yellow/orange. Any ideas, am I missing something? Also, new battery.

Not too sure, I re-did so much that day. I cleaned all batt. conections, pulled the fuse box and cleaned all those conections too. I had an o-ring missing on the intake, that let water in since it was rainy a few days before that, pulled the plugs and gave them a good cleaning, trying to start with water in the intake was hard on them, replaced my dist. the teeth showed slight wear, but I figured it was for the better anyway, and reset the timing, came from replacing the dist. It started right up after all that. Of course thats not mentioning that I also found out later that day that the Alt. was no good, so that got replaced too.

#219 of 375 2004 Tahoe won't start in the morning by 82z28man

Have a 2004 Tahoe that began giving me problems starting first thing in the morning. Replaced plugs, wires, and fuel filter - still had the problem. After reading other threads on here I began to suspect the fuel pump. The truck sits on an incline in our dirveway nose down. This morning, sure enough, it would not start. Rolled it down to the flat part of the driveway and it started. Took it down to the local GM Dealer and fuel pressure was only 40psi - should be twice that figure. $989.00 for parts and labor - lifetime warranty. 53k miles - fixed the problem!

I have the problem and found that if I am under quarter tank and park with the front lower than back it wont start. Roll flat and starts right up. Done this sense new.

Try the other key. Each key has a security chip in it, which is programmed to work with the computer in the car.
 
If that doesn't work, have the vehicle towed to the dealership with your keys, and they can reprogram the computer to accept the security chip in each key.
