just did a compression test
I was told to crank until the reading doesn't change. It ended up being about 10-12 cranks. Your numbers may be inaccurate if you don't crank it enough.

oh yeah i did it way wrong. i only took the one plug out at a time and i forgot to hold wot
Iv never done a compression test, but how does the car start if the spark plugs are out? and how long do you hold wot?
you dont want the car to start you just want it to crank over. so you take the plugs out 1. to install the guage and 2 to help keep it from starting. and you hold it in wot while cranking it just to let air into the cylinder

you don't want it to start obviously, you pull the fuel for the fuel pump and take out the spark plug
