Re: need your help (engine cranking)
No you need to crank on it to get a max, reading. Out of curiosity why do you want to do a compression test? Do you think you blew out a piston, or washed the bore? If you are concerned about a cracked block, head, blown gasket a compression test will not accuratly diagnose any of those.
