2006 Trailblazer Starting Problems
Visitors just bought this two weeks ago, 32k miles. Vortex 4200.
If you let it sit longer than 3 hours or so it doesn’t want to start. Only way to get it going is crank for a few seconds, wait, crank, wait on and on for 5 to 10 minutes then it will finally start and run great.
Any ideas? They have to return to the Twin Cities tomorrow and this stuff always seems to happen on weekends.
Have them try turning key to run, (dash lights up etc) not start & listen for faint hum from rear of vehicle. Do it 5-6 times, off-run-off-run-off, then see if it will start. If you heard hum first few times (fuel pump priming) and then not, try starting it then. If cycling key such as I described, allows it to start, I would lean towards plugged fuel filter, or fuel pump on its way out, but filter would be the place to start. Any prior symptoms, like hesitation, stalling, stumble? Chance of bad tank of fuel, add some conditioner/cleaner to tank, just to see if it helps? I’d do the easy, cheap tests first.
