On any car, with an electric fuel pump and Fuel Injection, it's been long recommended to turn the ignition key to the ON position and then wait a few seconds for the fuel pump to build up sufficient pressure on the Fuel Rail on the engine, so that the car will start when you finally activate the Starter.
This time delay, can increase with older cars, and finally may require a new fuel pump, new fuel filter, etc.
I can't remember how it was with my own Suzuki SX4, but on my current car, there is NO direct path to the NEG terminal on the battery from the Starter.
So it's important that every grounding point with the frame, is clean and free of any rust or corrosion. To minimize poor grounding on my own car, I connected a 24" battery cable, with eyelets on both ends, from the engine block to the NEG terminal on the battery. That assures perfect grounding for the starter in any climate or weather conditions.
Of course, with the so-called Maintenance Free battery, you can't service it or even tell when its fluid level is getting low, so all you can do is wait for it to fail and then replace it. I will only replace a Maintenance free battery with a FULL Maintenance battery with a cap for each cell, so I can maintain its fluid levels myself.
