Not starting on the first time is not a common thing to 3800's or a 3800 only thing. There's the good news.
To know why your car isn't starting let's explore what happens to start it. The key is turned and the fuel pump pressurizes the fuel system, the injectors prime the cylinders and the starter turns the motor over and the coils send spark to the cylinders.
Try waiting one second from turning the key to the on position before engaging the starter. That would lead us toward a fueling issue.
