starting problem

Has anyone had this problemI have a 2001 national marlin 5.9 cummins diesel. It has always run great. Started 2 weeks ago to move. Went out this week and weather was warm and would not start. I put in new batteries and she turns over great but does not start. I noticed the wait to start light does not go on. Also my OBD scanner does not show codes just says connecting. There is fuel but I do not think its working. Also air heater does not seem like its working. I checked fuel and there is fuel in filter but I do not see fuel pressure when I release a line. Plus I do not hear the fuel pump running when turning key on. I checked fuses and they look alright but it could be a relay or breaker which is what I am leaning towards. If I put ether in engine it speeds up but does not start. I feel its electrical because its multiple problems, like the computer is not working. It does not even try to start.

Check for a bad fusible link. I had mine break off on the back side of the main battery connector. Same symptoms.

If Dunner (RVM23) can't fix it, it ain't broke!

How cold did it get there in the past 2 weeks that it didn't start? Did you have enough diesel fuel conditioner to keep the fuel from gelling? (Unlike Dr. Scholl, it is not a good thing).

Its the VP44 injector pump. What a job to get out the air compressor is beside it but it does not have to be removed I don't think.
