I'm new in arduino, and what im trying to do is this one.
i've seen it in youtube and i want to know how it works and the parts it needed.
i already have the crankshaft position sensor (CPS).
it will be a big help if someone entertain me. 
Thanks in advance.

how many programmers does it take to change a light bulb ?
no need, just change the default to dark.
welcome to the forum.
one of the things we ask is that when you say you have something,, you post make/model a link or if you really don't know much, a link to where you bought it.
if you have that Cheap Piece of S$!t, er.... CPS....
what is that ?
if it has a way to give you timing, you should be able to use it like a switch and have it flash an LED.
in the video, there were 4 marks or clicks per revolution, with the clues so far, guessing it is for a 4 cylinder.
you can easily have the switch alternate in order with software.
you need to do some more research, find out how he fires the EFI, what voltage and how much power.
hopefully, you will get part numbers.
with some more information, we can help you put some of this together.
