trying to do a compression test on my 90 crx si? what needs to be done before i crank the motor?

I know i need to pull all plugs and unplug the distributer main connector but what do i do about fuel? What fuse do i pull if any at all???

 

I think I remember something having to do with the resistor box, I'll let someone else more experienced chime in here

 

well on my b-series i pulled all the plugs and disconnected the ignition fuse...that seemed to be all and it turned out fine

 

Just pull the 15a ECU fuse, pull all the plugs and hold it a WOT. Also make sure the motor is at operating temp.
