Was checkin things and tried it it started rite up , ran for a minute or two and same thing. Now it hasnt fired since . checked fuses . Any ideas?

Any codes? When was last filter change and do you get any air when priming?

Do you have a code reader? It may be a bad crank/cam sensor or something.

Any codes? Fuel gelled? Replace the fuel filter and prime the system again.

Holy smokes we all replied at the same time! "ANY CODES?"

........any codes? lol

Check your grounds, sounds like a bad connection somewhere. Forbannede eletriske problemer, lykke till.

More info? Do you have a tuner on it like an Edge? Your just north of me about 45 minutes.

scanner showed no codes, filter is good no air , have been plowin alot with it she is iced up pretty good.

You may have gelled fuel. With how cold it has been it doesn't take much. Full the fuel filter and replace. Fill new one with Diesel 911.

no tuner stock . had been running for about 3hrs before it happen all seemed fine.

do you run any fuel conditioner?

 

[mnnorskman]

i am guessing more towards a electric issue or ignition, it never missed a beat before or when it did start for that little bit. it ran smooth then it was like someone turn the key off

It will do the samewith gelled fuel. Thats why these guys keep saying that. Plus it the cheapest place to start.

When I had gelled fuel years ago it would idle and run up too 1200 rpms just fine but would die past that.

Did you have a liftpump? It may have pushed enough fuel through the gelled fuel to idle.

i understand the gelled fuel idea . dealt with that before, not with this truck on other diesels. I dont think that is the issue here thou.

my brothers 06 classic did that exactly 2 years ago

Well, if it was a bad sensor it would throw a code. If youve been plowing alot it might be something shook loose. I think some guys were having issues with the fuse box in the engine bay. One of them had to replace it and the other guy took it apart and found a bad connection or something. It is more likely something like that hppened to your rig. But it's never fun tracking issues like that! Check the 2 big Bail connectors over the drivers side valve cover.

No lift pump at the time.

So it cranks but won't fire. CP3 could be bad any way of checking desired vs actual rail pressure while cranking.
