disabling spark?

Hi i need to disable spark but keep the fuel system activated. will just pulling the EGI fuse do this or should i disconnect the crank angle sensor? yes i know this would probably flood my engine but i need to do this in one of my lab assignments for my class to test the "efficiency" of my cats, (even though i know my precats are hallow lol) its gotta be able to inject fuel into the engine but not have spark
Thanks! Much appreciated!

The EGI fuse would be the easiest route. If you unplug your spark plug wire be sure not to let them arc to anything else, could be nasty.

Not Sure..he didn't state what his car was.
If it was a Delorean if he disables the Flux Capacitor it would stop spark.Just reach behind the seat and pull the wires off it!
...
(state car Series and year in "the future"..)
