Is it at all possible that while your holding your phone you put different pressure on the key, such as holding at a different angle while turning it to start, than you do when you try starting it without using the phone? I ask because it may be possible the ignition switch is getting worn. Do you have a lot of weight hanging on the key?
#72 of 124 Re: loss of power when I turn on the defrost [burdawg]
Nov 13, 2009 (8:21 am)
I own a 2003 Trailblazer. Last night it started to idle funny. The rpms are normal then they slowly start to go way down the lights dim and just before it almost dies it gets a burst of power and the rpm's go back up to normal. I don't think it has anything to do with the defrost because I haven't had a problem with that until last night and I live up north and have been using my defrost for a month already. It stalled 2 times on the way to work this morning once when I was stopped at a stop light and teh second time when I slowed down to pull into my parking ramp at work. Any advice would be greatly appreciated. I have been told it maybe the fuel injections, oxygen sensor or fuel pump.

I am have a problem starting my TB for the past 3 months. It sounds easy, but that could fool someone also. It starts fine after running around town all day long. 10 or 20 stops. But over night, (first start of the day) I have to crank it over 7 or 8 times before it will start and then again run fine all day long.
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.

Has the fuel pressure and delivery flow been checked? Normally, with cold start problems I suspect the cold start enrichment, but that fuel level symptom wouldn't have anything to do with that.
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.

You know I heard that somewheres before on not being a trail blazer. Thats weird cause on my paper work it says 2000 Trail Blazer and the interior lining says Trail Blazer. On the emmissions decal under the hood it says 2000. Its a 4 wheel drive and 4.3 liter v6 -4 door.
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
#76 of 124 '04 Trailblazer EXT starting and electrical problem
Dec 12, 2009 (5:02 am)
I have an '04 Trailblazer EXT with 5.3 l. A problem started recently where the vehicle would act as if it had a battery going bad. You would put the key in the ignition, turn it and nothing would happen. I was if it had no power from the battery. The power level gets so low that many times you cant even remove the key from the ignition and none of the lights or anything work. If i hook jumper cables to it, all the power comes back it will start right up and run flawlessly and will show a full battery charge on the dash. It may go a day or a week or so before it does it again. I changed the battery 2 weeks ago and still did not fix the problem. Had starter and alternator checked and they showed that they were fine.
#78 of 124 04 Trailblazer - Won't Start
Mar 10, 2010 (6:40 pm)
I'm at a loss. I turn the ignition, all the bells and whistles illuminate, but the engine won't turn over. Aside from that, the vehicle is locked in park, and when I depress the brake pedal, the shifter remains locked. I've tried to jump it, and nothing happens. Battery is good. Wondering if the problem lies within the theft deterrent system.

Could be that. Also could be ignition switch, and there's other places it could be too. It's hard to pin it down without some troubleshooting. I think the first thing I would do is see if there's power getting to the starter solenoid when the ignition is turned to the start position.

Removed the starter motor, had it tested and it was no good. Bought a new starter, installed it, and the engine fired right up. Checked to be sure I could shift out of "park", and I could. Turned engine off, and then attempted to restart the vehicle. No joy. Same problem I had earlier. I haven't removed the new starter, but I have a feeling it is dead now. I believe there might be some gremlins within the electrical system, unless an ignition switch could cause all of this. Current state: turn the key to on position, fuel pump engages, but engine will not turn over. Vehicle is stuck in "park", as I cannot depress the shift release button.
