Cold starting a car used to be a complex process, but these days it’s a lot more simple.

Well, starting a cold engine used to be a complex process of depressing the accelerator for two seconds and releasing it, turning the key, and a whole bunch of different things like that. Then, if it didn’t start, you had to hold it to the floor and crank the engine. Well, all of that stuff is gone. See, fuel delivery in the engine compartment now is controlled 100 percent by the car’s computer and no matter what you do with the accelerator pedal inside the car or anything it really isn’t going to have much effect on the way the car starts. So, cold starting these days — get in the car, put your foot on the brake, turn the key, and it starts. That’s all there is to it.
