Yes there is a inductive heating flash. Now if they installed 8 new injectors to repair the hard to start issue that could have been done with the new flash I would seek counsel on that one. If that is what you are saying. JJ

Where exactly did you have this work done? More importantly, WHY were all eight injectors replaced? How did they determine all eight to be faulty?

In answer to your question regarding the "post key-off injector buzz" strategy, that is an OLD calibration that has since been updated with what's called the "inductive heat" calibration.

truck came in with cold start issues.after 15 to 20 minutes of running truck runs fine.they had no way of doing a cylinder contribution test cold .only operating temps.guess it would have been to much work to look at the spill over on the injectors with valve covers off when cold.they suggested replaci ng all eight injectors.the first thing i asked them was about the updates before they go any further.they said it had been done from what they were looking at.no buzz with ignition switch off when you switch it off.thanks for the info.i guess this fcim is way out of date.

ARE WE TALKING ABOUT A 6.0L OR A 7.3L? THE RED COLOURED CAPTION HOLDS TRUE ONLY FOR 7.3L. they suggested replaci ng all eight injectors.
BASED ON WHAT?the first thing i asked them was about the updates before they go any further.they said it had been done from what they were looking at.no buzz with ignition switch off when you switch it off.thanks for the info.i guess this fcim is way out of date.
Since you mention FICM, that's what made me assume you are referring to a 6.0L.

Dont mean to hi-jack but I have a question for you. I just had my FICM replaced and now when you turn the key before starting, the injectors do not buzz like the used to...Sound normal to you?

Yes, and I'm glad you asked. The most current up-to-date calibration does call for a MUCH quieter injector pre-cycling when the key is first turned to the RUN position just before starting. It bears mentioning that since a FICM replacement madates programming with IDS, it automatically loads the latest and most current calibration file into all three modules (PCM, FICM and TCM).
