#1 of 124 Engine won't turn over....everytime
Jan 16, 2007 (7:24 pm)
I have a 2002 Chevy Trailblazer LT, love it….well…. we are not getting along right now….The problem is that when I turn the key to the on position, you can hear everything power up (fuel pump etc), all needles in the correct position….go to turn it over….hear the click of the starter, but won’t turn over…change battery, changed starter relay, removed remote starter, had the front wiring harness replaced…no permanent solution.
The funny thing is if you giggle the key or move the steering wheel up and down….hold one foot out the window (just joking, haven’t tried that) you can get it to start… you can leave for x number mins and it will start….work fine for a week, month or so but continues to happen….I’ve tried boost it, different keys, spinning the new relay switch around….
My question is has anyone found a solution to this problem?

"if you giggle the key", are you sure that it's not just a bad ignition switch?
#3 of 124 spark plugs & rpm gauge,volt gauge
Feb 05, 2007 (7:10 pm)
can anyone tell me how to get to the spark plugs in a 2003 trailblazer v6 & one other problem which has not affected the running of this vehicle is the rpm gauge & the battery gauge.the rpm hand will be at 8000rpm at idle & battery hand will be as far in the red as it can go.i can disconnect battery cables & hands will work fine for awhile & then screw up again.this has been doing this for about 4 months.vehicle runs good as though gauges were working correctly.i know i probably need this fixed but i know its going to cost an arm & leg just for the dealer ship to look at it & its not causing a problem.

You need a new instrument cluster. The repair will be between 300-500 dollars at most dealerships, and you will probably have to wait at least overnight for the part to come in.

Try hitting the solenoid with a broom handle while someone is turning the key over... My starter checked out fine, until you try starting it... I change my battery, ign switch etc etc... Finally just decide to hit it and it turns over... (You can see it one the driver's side, so you don't have to crawl underneath...BTW you don't have to hit the solenoid very hard)
Changed the solenoid and haven't had any more problems...hope this helps. Please let me know!
#9 of 124 2004 Trailblazer - Ignition Problems and Stalling
Aug 30, 2007 (7:06 pm)
I've been having an intermittent problem (you know, the one's that never happen for the service dept) with my 04 Trailblazer.
Every now and then, when you go to start the TB, all of the gauges go crazy and dash lights are flickering. You can hear the various relays chattering. Sometimes, it will hit the starter briefly. If you turn the key off and on a few times, it will eventually start like normal.
It has stalled on me a couple times on the road. When it does, the gauges are doing the same thing. Bouncing all around, lights and relays chattering. Turn it off, try to turn it back on a few times, eventually it starts.
I've considered trying to replace the ignition switch, thinking that there may be a bad connection. I'm hesitant to just start replacing things - it's an expensive way to troubleshoot.
Right now, it happens about every other day.
Any thoughts, other than get something other than a Chevy?

You have a bad ignition switch. I'm surprised the dealership hasn't tuned into it, because you're having classic symptoms of a failing ignition switch. Had the same problems with gauges going crazy, wouldn't start, etc, etc. Eventually it will fail totally, so it replaced ASAP. Ignition switch is about $50, should be an hour labor at most dealerships ~ $150 total.
Edit: They can be hard to diagnose if you/they can't catch the failure. About the only way is to replace the ignition switch to be sure. The contacts go bad in them over time, generally due to the accessories being on at the time of starting the vehicle. GM is aware of the problem, and has an updated ignition switch.
