20 Most Recent 2000 Chevrolet Tahoe Questions & Answers

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!

Does it crank? As in does the starter engage when you turn the key to crank position?

Fuel injector problem , leaking fuel pressure regulator , Causes of gas in oil On my 94 Chevy blazer, gas in the oil was caused by a ruptured diaphragm in the fuel pressure regulator that is attached to the fuel injector. Flooding the engine. An over abundance of gas in your cylinders will wash down your cylinder walls and accumulate in the oil pan.

I do not understand what your question it, please elaborate. thanks
