can stiction kill an engine?

I've been noticing a stiction issue for the last several months - started rough, ran rough, eventually smoothed out when it warmed up and ran great. Changed to Rotella 6 last fall, that made it a lot better, but within a month, it was running rough when cold again. Kept meaning to get some rev-x and run it through, but what the heck, it goes away when it warms up.

The other day, it started real rough, but warmed up and ran fine. Next day, it no start at all. Couple of chugs when it cranks, but no start.

So... can stiction get to the point where the engine won't even start? Yes, I have four cans of rev-x on the way, but it won't do me any good if I can't get the engine to start and get the stuff circulating through the injectors... assuming that is the problem...

Have you checked your FICM? I'd do that before dropping in Rev-X (although I am a fan of Rev-X)

If it get to where it won't start cold, you can plug the block heater in, and that usually always gets it going. However, if you're having rough starts now in the spring and summer, you need to replace injectors. Rev-X and Rotela T6 are just expensive band-aids.

I'd check your FICM. Can cause problems similar to stiction if it doesn't output enough voltage to energize the injector solenoids when the oil is cold.

i'd start by checking your FICM voltage and go from there.

Throwing a code - injector circuit low, all 8 cylinders.

About a year ago, I checked for codes and saw injector circuit low on cyl 1. Didn't seem to be affecting running, so I didn't pursue it.

Sure is affecting something now.

FICM toast? Hope so, 8 injectors are going to cost some serious coin.
