I would leave the spark plug in the chamber and use a old spark plug. Plug it into the spark plug wire and ground it then crank it over. You can remove a spark plug but that will allow dirt to get in the combustion chamber when you crank it over and sometimes will throw the bendix out of the flywheel while your trying to do the test.
To test for fuel pressure crank the car over then find the pressure port on the fuel injector rail. It should have a metal cap on it like a tire air fill cap. With small screw driver push the schrader valve in (same as a tire fill valve) and fuel should shoot out. ***Be carefull to not get it in your eyes***. Maybe hold a rag to catch the fuel and make sure you clean up all fuel.
It is best to do the fuel pressure test on a cold car and make sure you have a way to put out a fire if one starts. Do the spark test before the fuel pressure test so you don't ignite any fuel with your spark test
