First class question and I understand that it is very common to the American market which seems to suffer greatly from not be able to get a vehicle started.
The most used way to get a vehicle to start is to greet it each morning with a snarl, and scream "Startyabastard", then turn the engine over. I am given to understand that this intimate verbal contact has a soothing effect on the reluctant vehicle, and usually it responds in a satisfactory manner.
I sincerely hope that this long tried method works for you, and that your motoring gives you great pleasure.
