The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

steering stabilizers are shot. I had the same problem, you hit a hole or bump and it starts to wobble then it resonates to a death wobble til you slow enough to stop it.

You need to have the front end inspected for damaged steering components. Check your Tie Rod ends, A frame bushings and ball joints to make sure there isn't excessive wear or lose connections. If all of that is in good working order Drive down the road with a friend in the next lane over and have them look to see if either wheel in bouncing. If either wheel is bouncing you need to replace the struts. they are replaced in pairs, both sides. The front end will need to be aligned after you do this.

    2002 chevy avalanche died at a stop light and now wont start back up. it just cranks.


    Those are known for having the fuel pump go out. Take the gas cap off, open the little steel door with a screwdriver and have someone turn the key forward, not cranking it over, just turn it until all the dash lights come on and see if you can hear the fuel pump kick on for about 2 seconds. You definitely need 2 people to do this. If you can hear the fuel pump then its probally not getting spark.

    Easiest way to replace a fuel pump on a 2002 chevy avalanche?


    i replaced the fuel pump on my chevy avalanche last year there is really only one way to replace it ,you have to take the braces down that holds the fuel tank up, unhook fuel lines, and rubber filler hoses, drop the gas tank to be able to get to the fuel pump. i bought a book at auto parts store that takes you step by step on how to do it.

    On my 2004 chevy avalanche just died one day when you star it starts but if you step on gas it losses spudders and dies


    Oh the list of things it could be is pretty long.
    Lets start with hmm bad TPS or plugged fuel filter? or underperforming fuel pump?

    Lets see if it was really sudden id start with checking the TPS among other things.
    If it happened kinda slow then id start with the fuel filter.
    Poor voltage to the ignition system can sometimes have that effect too.
