Thanks for any help.
THE ACCELERATION WOULD GO UP AND DOWN AS I DROVE .
HOWEVER IT SEEMS FINE WHEN THE OTHER CLIMATE CONTROLS ARE ON, SUCH VENTED HEAT. ALSO NO PROB WHEN THE RADIO IS ON.
THANKS FOR ANY HELP
thanks
I don't think that the ignition switch was bad i think something else is going on. No way that my brake switch and ignition went out over night. Anyone else have resolution to their issue. The truck seems to start kind of funny at first but idles and stays running.
well wouldnt you u know it the very next day it wouldnt start. to my luck this place was not open on the weekend. so the next time he told me to have it towed to the shop and he would take a look.yea ur right if i let it sit for a couple of hrs then it will fire up (strange). oh i glad to see that edmunds took the time to put this page together.
However, without fail, if you make a call on your cell phone while turning the key, it starts right up. We haven't needed it lately, so I haven't taken it to the dealer yet, but I'm trying to get a sense of what it could be before I go in.
Any clues why the cell phone does the trick?
Here is the kicker! On a FULL tank of gas it starts on the first or second try. On less than a half of tank it will take again 7 or 8 times before it starts. ( fuel pump or coolant temp. sensor or crank sensor???)
Fuel filters been changed twice since and installed new platinum plugs. 130,000 miles and been kept real nice maintance wise. Any suggestions will be appreciated. Thank you.

You know that there was no TB in 2000 though, right? 2002 was the first year. They were introduced somewhat early in 2001, but still were a 2002 model.
Anyways, good question on the fuel pump pressure. I heard this particular model has to be exactly on specs. If just 1 or 2 lbs. off it will not start! (no access to fuel pressure gage)
Maybe the float level has somthing to do with it? (shorting somthing out) or maybe a pickup tube has a hole in it?
The only other problem is an 02 sensor code keeps popping up and I have to erase it.
Stumped in Kansas. lol

I have the stalling problem, amongst others.
Last year, I almost lost my life on the freeway, when suddenly everything lit up and bells were ringing, my heart was pounding out of my chest and I pulled over to the side of the freeway, luckily, I was in the slow lane.
Each time I take it in, and by the way, I am under warranty, they say they cannot, "Duplicate the stall", and send me home, Last week I took it in, as the gas gauge was bouncing around and they replaced a fuel sensor, when arrived home, the car's whole dash panel flashed, and lost all power WHILE IN DRIVE!
At present, I have contacted attorneys for the lemon law, here in California. As my husband just died eight weeks ago, and I cannot afford to fix the car at all anymore, even still under warranty. I have also contacted Chevy. This IS not acceptable, since I am afraid to drive it now.
Engine stalled after about ten more minutes of rough idling and now won't start at all. Computer(not the dealer one) says pass-no codes. Nothing to clear or reset.
Next, dead battery and wouldn't even take a jump. New battery is good and lights up everything.
Won't start. Tries to start then pops the champagne cork for sound effects.
Service engine light remains lit. As do I !-)
Where do I troubleshoot from here? Any help is greatly appreciated.
TB dead in the driveway for now!
On a TB with 6 cylinder engine, locate the fuse box which is next to the battery.
Remove the two plastic covers of the fuse box.
The first (larger) cover has a diagram with the location of the fuses and switches.
(No.47) switch relay is top center in the fuse box, opposite end from where the positive/negative cables are connected into the fuse box.
Switch relay is square and gray color, sitting apart from other gray switches.
Remove (pull up on relay), then reinsert it back in same position.
TB started up right after that.
Thanks in advance. :confuse:

Does the dealer have any real answers?
Thanks
When you have the battery replaced, it is a good idea to have a second battery hooked up before disconnecting the bad battery. This way the computer will not lose its memory. Most reliable auto shops when replacing a battery will use this method when replacing the battery.
This happened to me and it took me several days of driving, starting, stopping before the computer reprogrammed itself. My trailblazer is now running fine. It is aggravating, to have to do it this way, but is cheaper than having the computer reprogrammed.
When you do get it started, how does it run? Smooth idle? Normal power?
No check engine light (yet). But did have before (on and off) battery replaced.
help!
Now that the computer thinks everything is great, it's not taking into account how dirty the Throttle Body is, and that's where your getting the bad idle.
Remove and clean the throttle body as soon as you can, (and yes, disconnect the battery while you do it again), and after it's all clean and you reconnect the battery, all should be well.:
And...yes:
here's the "how to":
