Although, I have the dreaded "early" 1998 model.

I did read somewhere that you are supposed to wait until the dash is done its sweep. Probably here.

Me too I read it on the Forum. Wait let things settle down then start the car. Sounded like good advice. Sure can't hurt.

I wait for the sweep and have pretty much waited in all my cars for the fuel pump to prime before starting.

I enjoy watching it, too. Let it idle for a bit afterward and drive her real slow till I feel she ready to be riden. Corvettes have a real life quality that reminds me of the west and riding horses in some abstract way.

I get in to start it I turn the ignition on and wait about 15 seconds for all the bells, whistles, pumps etc to settle down and then I fire her up.

Hey ... they have to wait for all the systems to power up in a fighter jet so why wouldn't it work on a c5?

Plus, it's kinda cool ...

Haha.

I was taught to wait on all fuel injected cars to give the fuel pump a chance to build proper pressure before starting.

The only thing I wait for is to say a little prayer before turning the key in hopes that the starter will not break a chunk off my engine block again... one new engine is enough!

I also wait for the gauge startup routine to finish with the thought of potential voltage drops and or spikes during cranking could generate false error codes or worse. I have seen in my computer electronics job IC devices work as intended until a voltage variation as little as 1/4 (.25V) or even less off from 5V fail. They are spec'd to run at 4.75V-%.25V but not always the case.

I was watching a "froggy" video on YouTube the other day, and he said, always wait until the gauges settle before starting the car.
Prior to that, I never heard that on Vettes.

Call it OCD.. I do the same thing.... turn on the key, wait for the bells, gauges to do the full sweep, then I start her up....

Sort of, but it's more a case of things happening at the same time. The description in the FSM implies that the gauge sweep is strictly an internal function of the IPC. I suspect that whatever scans take place elsewhere take far less time than the gauge sweep and other turn-on bells and whistles.

Also, it appears the PCM and BCM both need to be running and communicating or the starter won't crank anyway. (Theft deterrent runs through the BCM, clutch/neutral enable runs through the PCM.)

I agree about variation in 5V being a bad thing, but I don't see how waiting another 10 seconds helps. It's not like voltage drops/spikes become less of a problem at that point.

Seat belt first then turn key and wait for bells and whistles to settle then start. Once in a great while I get the pull key and wait but not very often.
