AutoEnginuity "Cold" Injector BUZZ TEST ?

Need help from folks smarter than me (basically 99.9% of the people on this site) LOL I have the AUTOENGINUITY "FORD Package". When performing a Injector BUZZ TEST, I know you should get an 'all on' master buzz and then a 1,2,3,4,55,6,7,8 individual buzz.

My question is will this 'BUZZ Test' operate the same on a cold/dead engine ? My tuck is down and I seem to get random results as opposed to last time I did it after running/warm and tha ALL ON, then each individual was really obvious.

Yes, the buzz test will operate the exact same way weather the engine is cold or hot.

Do you have a 6.0? You might want to search the term "stiction" both here and down in the 6.0 diesel section.
