start with a dry test first

engine up to temp
disconnect fuel pump relay
have a fully charged battery
remove all spark plugs

insert tester into first cylinder
throttle held wide open
crank over till gauge stops going any higher and read off the pressure :)

repeat for rest

should be around 150psi ideally and minimum of around 120
