If it were a key security issue you would have a code set. If no code then I would suspect another cause. Try this when it shuts off and doesnt start. Press the pedal about 10 percent and try to start it. If it will stay running only with 10 percent or more pedal I would suspect a sticking Idle Air Control Valve.
Hope this helps.

My 1997 chevy tahoe does not start right away.


Sounds like a starter problem, suggest you get it checked at your local trusted mechanic the next time it starts... If the starter is your problem it wont start for many more times.

99 Chevy Tahoe... Rear turn signals, brake lights, and hazards


I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

1998 Chevy tahoe Hard to start when cold


replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

Tahoe won't start


Is your security light flashing? If your Tahoe has the factory ant-theft system, if the security light is flashing while you are cranking your anti-theft system has been activated. It is common for the Tahoes to wear out the ignition lock assembly, lock cylinder and the ignition switch(electrical) which is attached to the lock assembly. I have replaced all three parts with great success and solved the no start problem on several GM trucks.

The most common problem with these vehicles is the fuel pump. The pump should run for a few seconds when you turn the key on before you crank the engine. If you don't hear the pump run, go to the fuse/relay box under the hood. Look at the diagram on the inside of the lid and locate the fuel pump fuse and relay. Check the fuse to see if it is blown put it back if OK or replace it. Unplug the fuel pump relay and use a paper clip to jumper across terminals #30 & #87 where the relay plugs in. If the fuel pump starts running, you should be able to hear it run at the back of the vehicle, where the tank is. If you don't hear the pump running, hit the center of the tank dead-center with a rubber or wooden mallet. If the pump still doesn't run, see if you can get to the wires going to the fuel pump and wiggle them. If you hear the pump run, try starting the engine. If it starts, replace the relay, if that was the problem or the fuel pump AND relay if the fuel pump was the problem. WARNING! WHEN YOU UNPLUG THE PAPER CLIP. IT MAY BE HOT!!!
The fuel pumps AND connector are big problems with GM trucks. If you replace the fuel pump(which is located in the fuel tank), use only the factory pump which you can buy at your GM dealer or an auto parts store that sells Delco parts. If the fuel pump used the small square four-pin electrical connector, replace it with the fuel pump. The latest GM/Delco fuel pumps will come with the new plug which you MUST change over as it is now a flat four-pin connector.
GOOD LUCK!
