Thanks - In the thousands of other sites where people post their car problems, no one ever seemed to provide enough description of the problems they were having to know if the problems were the same. All the others said "Car would not start - replaced ignition switch".
I think I will see if I can get the dealer to go ahead and replace it.
So glad I traded in my Toyota Tundra for this Chevy. ;-/
I put 150k miles and 7 years on the Tundra - had the brakes worked on at 120k. That's it. Never had it to a repair shop or dealer to fix anything.

I had the same thing happen to my TB at the gas station. Gauges and relays going crazy. Turned out that the positive battery terminal had gotten so hot that it melted the metal connector inside. Replaced the bolt inside the battery terminal and haven't had a problem since. So check your battery connections, especially the part that goes directly into the battery. Silly, huh but it's worth a try and could save you some money.

Doug I have this same problem in an 04 trailblazer ext.. They already changed my ignition switch it didn't fix the problem.. It happens intermittently for me though. Like once a week and the last time it took 5 times to start it.. I hope yours is the ignition, but it wasn't mine. We changed it 3 weeks ago and it happened to my husband today. Ours only occurs when starting it whether hot or cold, not while running already.

Sometimes, I wonder if it isn't the Starter, but often the problem begins before I have turned the key all the way to engage the starter.
I suppose I could have a couple problems...

Check your battery connections and replace or clean them. I bet this solves your problem.

I just dropped mine off at the dealer this afternoon.
I was able to get the problem to occur for the tech. He almost instantly said he thought it was a bad connection or bad neutral switch in the gear selector column.
I should know tomorrow. I'll post an update, hopefully to say that it was just that simple.

I picked it up from the dealer Friday. They replaced the ignition switch.
So far, it is running fine. The intermittent problem was becoming a persistent problem shortly before I took it to the dealer. It actually shut off on me on the freeway going to the dealer to drop it off. It was also getting to where 3/4 of the time, trying to start it would foul up.
From everyone elses' descriptions, it sounds to me like any bad electrical connection in the chain from the battery, through the ignition, to the starter will cause the symptoms described.
Some of you said that you replaced the ignition switch but the problem came back - I'll cross my fingers, and will repost should the problem come back.

Well I too got mine back.. They had to replace the PCM.. I guess it finally did it for the tech and it also registered a code for wires.. Well I guess the two codes I was got have only appreared in 8 trailblazers EVER made! None of them know exactly what the issue is lol.. sooo each one replaced either the battery, PCM, ignition swith, and like 2 other things.. Since we have already done the switch they went ahead and replaced the PCM I really hope this fixes it! I am 3 months pregnant and have a 7 month old, the last thing I need is to be stranded in Indiana in the snow because of this! I hope your problem is fixed Doug!
#21 of 124 2004 Trailblazer-what's the problem
Sep 27, 2007 (5:08 am)
First, let me say I know nothing about cars and am a woman, but I am looking for advice as my my Trailblazer is parked in front of my house, and I am home with 4 children. My husband says this will cost $300-400, which we can't do right now, but I am not sure what is wrong. (our warranty is expired, of course!).
Monday after ball practice, I got in the car and when I started it, the lights flickered and wouldn't start. So, one of the parents jumped it and got it started. After getting it home, it won't start again. My neighbor used his battery charger to charge, and it did, but still wouldn't start. The lights are all bright and the radio and such all work, but it still won't start. Both my husband and the neighbor have said the starter, but after reading some of other posts, I am seeing other related issues.
Can anyone give some advice? Help!
