Crank but No start...... Kinda???

2012 6.7 PSD / 23K miles / DPF delete

So truck has been running fine.... (Other then blown intercooler pipe about a month ago but replaced and no problems since then). Anyways left a Christmas party and drove home, which is all of about 2 miles, with no problems. Went inside to do a couple of things which only took about 5 mins. Went to leave again but the truck would not start.

It cranked and turned over just would not start. I tried 3 times and each time had the same problem. I am no expert but I would describe the noise as a "grinding" noise?? After the 3 attempts with no luck I turned the key all the way to off and tried again... She started right up! Drove her around and did what I needed to do with no problems. When I got home I tried to get her to do it again but she never did. Anyone ever have this problem or have any idea what could have caused this??? Anything I should be watching out for?? Thanks in advance!

Not having the frame mounted fuel filter tightened to the stops can cause this. Puts air in the fuel. I also had a no start issue. Turned out to be a sensor that "rotted out" according to the dealer. Not sure of the sensor though. Did something similar to yours. Wouldn't start occasionally and progressively got worse to the point where it wouldn't start at all.

do you still have a functional throttle actuator/valve assembly?

As far as I know I do. Please forgive my ignorance but not exactly sure what that does. I haven't done any other mods than the DPF delete w/ pyro.

reason I ask is that my truck has done the exact same thing and finally found the throttle actuator was stuck closed not allowing any air to enter the engine.

When you say grinding noise, what do you mean. My 2011 starter engaged to soon and knocked a tooth off the fly wheel. That gave me a terrible grinding noise that was random and would not start at that time. Other times it worked fine. Took 3 trips to my service center before I could describe it good enough for them to figure it out. Ended up needing a starter and flywheel

When i would hold the key over to start all it would do is make the grinding sound. I would return the key to run and try again with the same problem. It did it about 3 times until I finally turned the key all the way back to off. Once I did that it started back up. Idk just seems more of an electrical issue to me then a mechanical one since turning the key all the way back to off fixed the issue. I have not had any problems since then.
