RE: Fault Code 1117
Update. First a thank you to Rawze for pointing out I needed a suppression or flyback solenoid.
This is a pretty old engine so some may want to skip this. Did did not have to add the kickback diode because ECM got replaced. I did not list all the problems with this engine. Obvious problem was occasional lose of signal to fuel solenoid which is why I added another key switched wire. There were other issues.

Truck is water tanker for a local VFD. First problem was I couldn't make sense out of a couple of codes Insite was showing .One code I couldn't even find. Learned that Insite doesn't work well with these very early N14's. Cummins had a tool back then called Echek. Was able to get the use of one. Codes about the same but some difference in definitions per the manuals included with the Echek.

Almost all pointed to the ECM. Some circuit checking reinforced that diagnosis. ECM NLA from Cummins. The local Cummins location which is a Cummins only facility, not part of a truck dealership, recommended a rebuilder. This location has a bunch of 20, 25, 30 year people there. Usually good info and work.

Based on what I have read here and other sites I did not want to be involved in getting the ECM. Passed info to customer and let them get it. We then installed it. All the codes cleared and stayed cleared. Running and intermittent misfire/stumble/smoke issues also cleared.

Something interesting about the Echek. Small private fleet that let me borrow the tool has a guy that has been with them since the 855 days. He told me he was pretty sure that somewhere in the past Cummins had put out a field letter saying not to use Insite on the N14's.

This post should probably be on an antique engine board somewhere!
