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.

 

i don't know if your system will but my snap on system will. it is not reccomended to do on a cold engine you might get inaccurate results....

good luck

 

I ohmed each side of all 8 injectors on a 63 degree dead cold engine. The results of ALL injectors was between .8 and .9 OHMS.

 

Doing a buzz/click test on a cold engine will better indicate if there is a cold stiction issue.

The injectors may not click cold because the spool valves are varnished up or scored.

 

yes it will be better on a cold engine
