I reset mine at least 4 or 5 times during my attempts to correct the problem and it was not a solution. Right now I thinks it was due to bad gas...

The wide spread issue of cold staring problems is where it doesn't start at all the first time you try to crank it over in the morning.

What you had in the first video is not the typical "cold start" problem.....

I fixed mine by changing the fuel pressure regulator attched to the fuel rail inside an aluminum housing, and replacing my injectors. Both of these parts have small rubber O rings. This area is subjected to huge amounts of trapped heat from the bottom of the intercooler and the engine manifold. My O-rings for all parts were brittle, and thus not keeping the proper amount of pressure in the fuel line after sitting for a while...and I am sure the injector O rings were an issue as well.

Since August, I have had no cold start issues, and matter fact, starts up better than it ever had before, instantly.
