Well, I had to get another vehicle to use as the ol' diesel was not starting in a reasonable amount of time.
When I got time and money, I did the following things:
1. Replaced the fuel filters.
2. Replaced the glow plugs.
3. Replaced ALL of the injectors.
4. Changed the oil and put in new filter.
I charged the batteries and tried to start it. It took a lot of cranking and then recharging (good) batteries. Finally, after hours of trying and charging, then, after all the cranking and rumbling, coughing and sputtering (while it was purging the air out of the fuel lines), it began to run normally.
I shut it off and when out to start it the next morning (about 72F) It took a lot of cranking before it would run!
I say that because it would often start and run smoothly for a few seconds and then shut off like I turned it off! It was the same as before the air was purged and before I did all those items above. After a long time, and a lot of cranking, and a lot of running for a few seconds then cutting off, it finally started running (under protest). I figured I had more air that didn't get purged, but after awhile it began to run normally and it settled down. I drove it for 2 hours on the interstate and up and down hills. If I stopped anywhere, it started back up right away.
Of course this morning it is the same old thing. I checked for codes but found none.
The only plus side to this is that the injectors needed replaced. It runs much smoother and with more power than ever (when it starts).
It looks like a trip to the dealer and I just don't have the $$$ to go through this.
Anybody got any ideas? Anyone? Anyone? Bueler?
