i started the removal of my engine to replace some oil seals and gaskets. mean while my other brother just bought himself a compression tester today and i was thinking what i could get away with doing a test on my engine. the engine still sits in the car, the coolant is out along with gas lines off, crank and cam bolts loosen. Serpent belts are still on. intake piping is off along with exhaust headers. my question is whats needed to do the compression test on my engine at this point.

Unscrew the spark plugs, put in the compression tester, and crank the motor.

All timing belt related components need to be installed and the starter needs to be secure and functional.
It sounds like you can tighten the crank and cam bolts and be good to go.

Yes you should disconnect the fuel pump plug under the back seat.

i just finished reading the packaging manual, its says i need to let the car run for 5-10 mins. i cant because of the state the car sits at. can i still get away with not letting the car run, it say something about adding a spoon of oil to each hole if my reading are off.
