After pressing start does it stop automatically? Is there a mode that pulses the injector for a certain time then stop?

You can have The tester have a countdown and after the countdown is over, it stops pulsing the injector. There are different modes, different pulse frequencies and different counters all adjustable

Will this tester work with injector on car? i imagine you flood your cylinder with fuel?

YES IF THE FUEL PUMP IS RUNNING ,THE BEST THING IS TO REMOVE THE INJECTOR TO TEST, BUT THE FIRST THING IS CHECK THE RESISTANCE OF THE INJECTOR TO IF IT SHORTED...

Do you think this would be able to control 4 injectors at the same time?

You can make a second circuit with a mossfet/transistor triggered by this device as a signal to controll any number of injectors you wish.

Will this work on a GDI injector?

THIS TESTER WILL NOT WORK ON THE GDI INJECTOR
