The time of the year may not be helping you. With your use of km, I'll guess you're in Canada, or close to it. I think you may have more than one issue, GP's being one. If you have tested the GPR and it's good, you should ohm out the UVCH to check the GP's themselves. A quick, non-technical test of your GP system would be to plug it in over night. If it starts up quick and easy and life is full of dreams and rainbows, something is wrong with the GP system. If it starts easier, and still gives you issues, it would be time to look at other things, but let's go one step at a time to eliminate the easy stuff.
A few starter questions though.
When was the last time the oil was changed? These diesels require good oil to run right.
When was the last time the fuel filter was changed? Starving of fuel would be problematic.
You asked about priming after a fuel filter change, so I can guess you haven't changed it since purchase. That leads me to assume you haven't changed the oil either. Whether they're the issue or not, both of those should be done. I would also get a transmission fluid flush as well. All of these will set known maintenance benchmarks for your own cycle.
Hucorey is correct in the no priming after a fuel filter change. I don't even refill my reservoir after a change. I throw in a new filter, turn on the key for a few seconds, turn it off for a bit to let new fuel soak into the filter, then I turn it back on, fire up the truck and drive it like nothing happened. Easy stuff.
You don't have to let the fuel soak in, I've done a change and fired the truck up and hit the road with no noticeable problems. But if giving it a chance to prime has a slight chance of making my injectors not commit suicide early, I'll take it.
