How do you disconnect teh fuel system? I just pulled the throttle cable off the TB. I don't want to be dumping fuel into the system as I crank. Thanks

 

remove the fuse, right on the left fender well! The cable wont stop the fuel pump from priming the system.

 

I would do more than just disable the fuel system:
#1 Unplug each bank of coil packs from the main harness. Its the large connector in the center.
#2 Unplug each fuel injector.
#3 Hold the throttle open while cranking it over 5 or 6 times or until the needle stops climbing.
You should have 190-210psi on each cylinder

 

Yeah, forgot to finish huh? Its always the little things. I do recommend making sure you crank each cyl an equal time, or crank. Helps ensure your comparing apples to apples.
