2001 chevy tahoe after driving the vehicle

To disable the alarm system in a 2001 Chevy Tahoe, try the following steps:

1. Close all doors and windows.
2. Insert the key into the ignition and turn it to the "ON" position.
3. Within 10 seconds, press the lock button on the driver's door five times. The alarm system should turn off.

Note: The above steps assume that your 2001 Chevy Tahoe has a factory-installed alarm system. If it has an aftermarket alarm system, the steps to disengage it may be different.

Sounds like the wiring harness connection in the back of the speedo cluster is loose. This will cause crazy reading and the vehicle will perform like normal... sound about right??

Sound's as though a previous owner installed a speed governor so that the engine would not exceed the nationwide 55-65 mph speed limit average. This most likely was a company owned vehicle or owned by someone concerned about speeding ticket's or excessive speed by a teenage driver. It can be uninstalled by an experienced mechanic. Unless this poses a problem while driving on an interstate, you may wish to leave it as is.

Is it closer to the back of the vehicle or the front?Possibly the fuel pump. Try opening the gas tank and stick your ear close to the intake of the tank while someone turns the key.

Hello! There are power steering fluid in/out hoses but no vacuum lines...It sounds as if the pump needs to be bled of air or the belt is loose...Belt should move about 1/2 to 3/4"...Bleeding is as follows...
Guru...saailer

ImportantPower steering fluid level must be maintained throughout bleed procedure.

1. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.
ImportantWith hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.

2. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
2.1. Start the engine.2.2. Firmly apply the brake pedal 10-15 times.2.3. Turn the engine OFF.
3. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle in General Information.
4. Key on engine OFF, turn the steering wheel from stop to stop 12 times.
Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.

5. Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid .
6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
7. Verify the fluid level. Repeat the bleed procedure if necessary.

Separate fuse for low beams a possibility. Alsto check for a bad ground or bad power connection to the bulbs.

tranny went out also check the tranny linkage

turn 4x4 switch off put vehicle in neutral then put vehicle in reverse and drive in reverse a couple of feet the put it into drive and it should come off of 4x4 if not then repeat until it comes off

the only thing i could think of is a fuel shut off switch malfunction

replace fuel pump relay. check all fuses to ignition and pcm .make sure they are not loose. check coil wires make sure they not loose.look at battery if you have the ac delco seal battery make sure green eye still there .if its black have battery check out.
