ok so unplug the thing and stick a voltmeter in it, the hot side is obvious-if neither side is hot then you know you need to start troubleshooting the circuit-I would start with the brake fuse.

Get a 12v tester and use it to find your hot wire usually the blue wire but it changes depending on where the truck was built.

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.

Go on google or bing images, you might get a picture that helps. If not find your local garage or DIY neighbour to help. Do you mean the steel door strap? In which case you may have to access the inside of the door by removing the trim panel. But I would have thought it was all accessable from outside with a socket or 2.

Usually this is caused by the exhaust, and most common is the heat shield around the catalytic converter. Sometimes these can be spot welded, by I have fixed a few by putting together a few large stainless hose clamps and placing all the way around the unit and tighten them up. Sometimes the rattle is internal, and replacement is the only option. If so, rather than getting a very expensive stock replacement, you can by a universal easy flow hot rod type for about $100, plus installation.

There is one sensor and several solenoids. The temperature sensor is the only sensor. The rest are solenoids. To replace the temp sensor, you have to remove or replace the valve body, depending on your expertise.

Pull out the bulb, it is probably black. You probably touched it with your finger when removing it or reinstalling it and it blew out, either that or the little tip on the bulb got broken off. Either way it will need to be replaced.

Check that the heater core's two tubes that enter the firewall are getting hot. If they are, then you are having a blend door problem which will require disassembling the dashboard instruments to get at the vacuum motors that control the blend doors.

If the heater core is not getting hot at both tubes, then the following procedure outlines how to change the heater core out:

Removal & Installation

Heater core removal

To Remove:

  1. Remove the HVAC assembly.
  2. Remove the heater core cover screws.
  3. Remove the heater core cover from the HVAC assembly.
  4. Remove the heater core gasket from the core.
  5. Remove the heater core from the HVAC module assembly.

To Install:

  1. Install the heater core to the HVAC module assembly.
  2. Install the heater core cowl gasket to the HVAC module assembly.
  3. Install the heater core cover and screws to the HVAC module assembly.
  4. Install the HVAC module assembly to the vehicle.

Are you serious???? This is your description for a problem that could have 10,000 different causes?

2000 Chevrolet... | Answered on Jul 01, 2014

more than likely that it is either ba crankshaft position sensor if it has one or ignition module because they build resistance when the copper windings inside them get hot on the crankshaft sensor or when the ignition module heats up they begin to fail its very common for these things to go bad on chevrolets also you might want to look into your fuel pressure because fuel pumps also begin to fail in this way you described when they are worn out and when they cool down they work again
