First NO START ever

[Gdawgs]

I've experienced this several times with various vehicles, a Yaris, a 2001 Sienna, my kid's 2006 Camry, a 1995 Dodge Neon, and a coworker of mine had it happen to his Camry.

In every case, here's what happened. The engine was completely cold(had been shut off for several hours), the car was started very briefly (for example - back it out of the garage), then the engine was shut off, then the car sat for a long time(several hours/over night).

Then when you go to start it, it acts like a flooded engine back in the carburetor days.
Typically, if you keep cranking on it, it will eventually start, probably smoke, then run rough for a little bit.

My coworker had his towed to a shop, and the same thing. They got it started, it ran rough for a bit, then was fine.

I can't speak to any engine codes though, I've never checked.

Now, I never do a short engine run like this. If I have to back my car out of the garage or move it a short distance on a cold engine, I always take it for a short drive first.

Not saying this is what has happened in the instances posted here, but a possibility.
