Does anyone else wait when starting your car?

Like I said before, my '99 which I had for 3 years started, and my current 2000 car, start within 1/2 second after turning the key and I've NEVER had any kind of problems whatsoever not waiting for the gauges to "cycle". Get in, turn the key, let it sit for a few seconds to build up oil pressure, and drive away, quite simple really.

Never, and I've had two C5's. And there's no problem since the LMC5 has been installed in my 2000 either, for way over a year now. I think this is all nonsense, and I would like to know where this came from.

If you guys fell that doing this helps your cars in anyway than by all means continue to do so. Is this process strictly for a C5 or is it for all cars and trucks that have gages that sweep when you start the car? Other than this site I have never heard of this, and believe me take what you hear on here with a grain of salt so to speak. I have owned my corvette and several others cars and never had any reason to believe that I was doing any harm by not waiting for the gages to sweep. I own every mile that is on my car and never had a code because of not waiting for a sweep of the gages. Never an issue with start ups even after a long period of sitting

Like I asked before, if this was a problem not doing it, or if it was beneficial in any way, wouldn't Chevy, the manufacturer of the car recommend it or tell you to do that? IMO this is all hogwash, but if you feel like you are accomplishing something, go right ahead and wait as long as you want, just don't deplete the battery doing it.

You are comparing apples to oranges. Your car is not looking for Internet connections or antivirus scans that keeps your pc from turning on instantly.

Of course not, but it must have other tasks to do before startup. Does it finish them all in a millisecond? Other computers take time to get ready to start.

(Pretty sure the BCM doesn't, what with that 20ma current draw.)

No idea exactly how long it takes, but recall what I said in post #37: if the BCM and PCM aren't up and running, the starter relay won't trigger.

Microprocessors from the '70s and '80s were quite capable of reading and processing signal levels much faster than things like relays operate.

It's all relative: "slow by today's standards" is still orders of magnitude faster than the electromechanical systems that the computer controls.

I usually wait for the gauges sweep before starting. I have had the ABS Warming Up alert a couple of times, primarily if I start before gauge sweep. Usually goes away though after a few seconds.

Necessary or even desirable? Meh, not so much.Waiting for the fuel system to pressurize is the only real rationale I've seen, but I doubt that takes anywhere near as long as the gauge sweep.

I get in, clutch to the floor and fire that sucker up. No problem. I don't even think about any acceleration until the fluids warm to proper temperature. I think that's probably where most hose things. Hitting it hard too soon.

(Note that the owner's manual uses the word "normal" to describe that message and says that it's temperature-related.)
