The other thing you might want to do is to blow out the spark plug area with compressed air BEFORE you remove the spark plugs so grit, grime, and other garbage does not get into the cylinders. If you do not have access to an air compressor, you can go to a convenient store and use their tire pump. The compression test should also be done on a warm engine.

I wasn't quite sure of what the OP was talking about.
Turn your jeep on and then pull the fuel pump relay until it starts to bog down and die. That should de-pressurize the fuel rail. To be sure you can check the shrauder(spell check) valve.
