the starter switch serves to spin the engine up to a speed at which fuel can be introduced via the two cutoff levers just below the throttles on the pedestal. In order to start the engines on the default 738, the starter switch must be engaged first, then when the EICAS reads a N2 value of 20%, the fuel valves should be opened. A successful start will give a noticeable increase in engine pitch and N1 values. After the engine has stabilised, the starter switch will automatically return to its running position.
On a separate note you mention having to shut the aircraft down on first entering the simulation. To avoid having to do this, load up the default C172 at an airfield of your choice and switch everything off; mixture, battery, avionics master, etc. Then save the flight by pressing ";" Give the flight any name, and tick the box saying "make this the default flight". By doing this, the next time you load an aircraft in the simlation it will already be in the "cold and dark" configuration and you can get on straight away with the startup drills.
If you have any more queries about the 738, you can find checklists on the kneeboard (SHIFT-F10) that will guide you through the procedures for all flight regimes. It also contains useful reference weights and speeds you can use for flight planning.
Hope I've been able to help you!
